Tarsius spectrum(marmoset) unique animals that live in the woods tangkoko batuangus National park




Tarsius spectrum(marmoset) unique animals that live in the woods tangkoko batuangus National park,Bitung city,North Sulawesi,Indonesia.
Scientific classification
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Primates
Family: Tarsiidae
Genus: Tarsius
Species: T.spectrum.
The spectral tarsier (Tarsius spectrum also called Tarsius tarsier) is a species of tarsier found in Indonesia. It is apparently less specialized than the Philippine tarsier or Horsfield's tarsier; for example, it lacks adhesive toes. It is the type species for the Tarsius genus. The Spectral Tarsier (Tarsius tarsier) is less adapted than the Philippine Tarsier or Horsfield's Tarsier; for example, it lacks adhesive toes. It is the type species for the Tarsius genus. It is found in Indonesia, primarily in the lowlands of Sulawesi and on Selayar Island.
The Spectral Tarsier has the largest eye to body size ratio of all of the mammals.While its range used to include both the population on the island of Selayar as well as on nearby southwestern Sulawesi, the latter populations has been removed to a separate species, Tarsius fuscus.
When considered to include Tarsius fuscus in measurements females weigh between 102 and 114 grams (3.6 and 4.0 oz) while males are 118 to 130 grams (4.2 to 4.6 oz). It has a head-body length of 9.5 to 14 centimetres (3.7 to 5.5 in) and its tail length ranges from 20 to 26 centimetres (7.9 to 10.2 in). The average lifespan in the wild is thought to be 10 years, however in captivity the closely related Horsfield's tarsier can live up to 17 years and it is thought the spectral tarsier may have a similar longevity.(source:wikipedia.org).

Lembeh Strait,Bitung,North Sulawesi,underwater paradise of the most beautiful in the world





Diving in the Lembeh Strait
Lembeh Strait the new wonderful for diving,No place on the planet gives you the chance to see more shy critters such as the mimic octopus, flamboyant cuttlefish, harlequin shrimps, skeleton shrimps and innumerable nudibranchs,The fish also include the usual tropical reef suspects but also the more bizarre: Ambon scorpionfish, snake eels, stonefish, sea robins, stargazers, devil fish and even the weedy scorpionfish. There are also beautiful seahorses including pygmies, pegasus, mandarinfish, ghost pipefish and the endemic Banggai cardinalfish.

Dive Site Descriptions

Aer Perang
The formation of this dive site was influenced by a World War II warship that blasted through the rocks in order to reach fresh water. The name literally means 'War Water'.
Angel's Window
If, during your stay, you are growing tired of black sand, among some of the most amazing and bizarre, rare creatures on the planet, Angel's window gives you the chance to do a bit of reef diving. More than just a change of scene, however, this site is in fact a beautifully decorated pinnacle whose tip lies just below the surface, off Lembeh Island.

Hairball.
As you listen to the dive briefing and look at the site map you may feel a sense of déjà vu. The muck diving sites all sound the same - gentle slope, black sand, patches of activity, a few sunken logs. Hairball however, often emerges as a king among kings in the Lembeh Strait.

Jahir.
Jahir is one of the newest dive sites discovered in the strait and was named after the guide who first found it. Jahir is a site that in many ways typifies Lembeh, with black volcanic sand that you will slowly cruise over with your nose close to the sea-bed.

Makawide.
This spot is situated between 2 large boulders rising out of the ocean which offer amazing scuba diving opportunities over coral patches as the gradual slopes descend beneath the waves of the Lembeh Strait. Despite being right in the middle of the channel, currents are generally calm.

Mawali Wreck.
This Japanese World War II steel cargo ship wreck lies completely on its side on the strait's seabed in water ranging from 15 to 30 metres. As the sight of the wreck begins to take shape beneath your fins you will marvel at just how beautifully encrusted it is with crinoids, black coral trees and soft corals.

Nudi Falls.
Your diving boat will tie itself to both a low impact anchor as well as some over hanging trees at this site near the water's edge. The sheltered nature of the bay and the proximity to the land makes it feel like a lake dive. You will notice, as you roll over the edge, that the water is normally a degree or two cooler than at Bunaken.

Nudi Retreat.
This is yet another great site featuring a gentle reef slope that starts from a sheltered cove on the Sulawesi coast and descends gradually to a depth of 28 metres. Offering more coral than many of the dive locations you will find on the Lembeh Island side of the strait, healthy soft coral and anemones abound, playing host to probably the world's most popular fish, the anemone fish.

Pantai Parigi.
Believe it or not, Pantai Parigi is actually the only white sand muck dive site that you will find in the Lembeh Strait, an area dominated by black sand. This bay, on Lembeh Island itself, has exceptionally healthy and dense coral cover in the shallows, then a gentle white sand slope. This site is named after the fresh water well in the village and the nearby beach: "Pantai" means 'beach' and "Parigi" means 'well'.

Police Pier.
If you scuba dive here it is likely to be at night. Nighttime and muck share the promise of discovery, so to do a night dive in a place like the Lembeh Strait should be something special, and it is. Police Pier may be an odd name but there is every chance of a 'Sting' coming your way as scorpionfish and lionfish lurk all around. The bottom composition is a dull grey mass, at first glance lifeless but on closer inspection, teeming with activity.

Teluk Kambahu (TK 1).
A manageable name for a site which translates as the name of the local Lembeh village bay. Another entry off the boat into shallow water will see you descend over a dark sandy bottom, sloping gently down to 25 metres. To dive here is to snoop through the rubble and in and around sunken bit of wood and nets. Your possible discoveries could run into ridiculous numbers.

Dive Spot Area,Bunaken Island Marine Nasional Park.




Dive Spot Map_Bunaken Island Marine Nasional Park.

With many wonderful sites to choose from, the Bunaken Marine Park stretches over 75,000 hectares in the deep waters of the Sulawesi Sea. There are five islands that make up the park, Siladen, Montehage, Nain and of course Bunaken. The fifth one Manado Tua stands out quite literally as it is a magnificent extinct volcano which dominates the four others and the skyline from the panoramic view from our jetty.The beautiful corals here are to be found surrounding the islands and with a depth from 3 meters to 1300 are home to the many species or sea life to be found here, definitely making this a unique diving experience.

With drift diving being the order of the day, we let you "go with the flow" (we do try to avoid up & down currents where possible!) Let your highly specialized dive guide find you the wonders that so many guests will drift pass. Keep an eye on the "Blue" for larger pelagic.
With the water temperature an all year round 26-29°C it is a destination for all seasons, with March to October being the dry season, and the rainy season starting around November through to March/April. The hottest/sunniest time tends to be June to September, but whatever the Month, don't forget your sun cream!
Although primarily a dive destination, the shallow reefs are also a haven for many different fish, starfish and corals, possibly even turtles, thus making it a wonderful experience for snorkelers also. With the coral disappearing into the deep, that's where you will discover so much more! Due to the depths here, we recommend a maximum dive depth of around 25-30 meters, depending on certification.
Here is an idea of some of the dive sites; we do also have a fantastic "house reef" situated a few minutes off the jetty, as well as some other nearby sites that are well worth visiting such as Walet point, Coconut Cove & BMJ.

Tasik Ria Area

Critter Circus 1 - 2 - 3
Located right in front of Tasik Ria Resort & Tasik Divers, these three sites run into one to another. Critter Circus is a gently sloping continuous reef with interesting critters to be found whereas Reef Balls got its name from those artificial concrete Igloo shaped structures, which have been dropped on the sandy slope and have become a perfect habitat for a wide range of interesting critters, including different types of pipefish, leaf scorpion fish and flatheads. The most amazing part of this area is the extensive sea grass beds in the very shallow area. Literally hundreds of pipefish can be found here, fingered dragonets, clown and warty frogfish, sea snakes, and nudibranchs.
Popo Betlehem
A wordplay coming from "Better than Lembeh", describes this site perfectly well. A true "muck" dive like those found in the Lembeh Straits, but with warmer water and better visibility. In the shallow water extensive beds of Sea grass are found, where you can find different kinds of moray eels, pipe fishes, sea snakes, nudibranchs as well as seahorses and Frogfish. The black sandy slope has hardly any patches of reef but is full of concrete and sand filled bags with ropes attached, which hold the Oyster farm in place, which floats above water. Those offer excellent hideouts for an amazing array of critters and the ropes are used by big schools of long finned squid to attach their eggs. The whole range of "special" critters can be found on this site and photographers can easily dive here for days and days.

Carlos Point
Just 5 min navigation from the TR house reef, another gently sandy slope of patchy corals and black sand. Ghost pipefish, lager groups of cardinalfishes, and sandy dwellers like jawfish and lizardfish are very common.

Tanjung Kelapa
Who said that wonderful coral walls are only around Bunaken? Tanjung Kelapa starts with a white sand slope that continues in a vertical reef with hard and soft corals, gorgonians, and schooling black snapper all around. A must-see of the area.
Bunaken Island
Arguably the best sites around Bunaken are Lekuan 1, 2 and 3. These are really the same site, but with so much to see are separated. With more shelter here and lots of large nooks & crannies to explore, you are more likely to find larger fish like Napoleon wrasse, bumphead parrotfish along with sea fans, giant sponges and turtles.
Lekuan 1
Another long beautifully covered reef, located in front of Bunaken Island, which seems impossible to be done in one dive. With visibility often 30 to 40 meters, sightings of larger species such at blacktip sharks, turtles, and schools of trevally and Napoleon wrasse are very common. Start on the sandy slope, which slowly get into the wall part of the site. Bannerfish and Napoleon Wrasse are resident in this famous diving spot including school of Pyramid Butterflyfish. Small whitetip reef sharks can be found sometimes here sleeping in crevices.
Lekuan 2
Continuing the first part of the famous long reef located in front of Bunaken Island is Lekuan 2. It is a vertical wall covered with different types of hard and soft corals, which have beautifully decorated this site and welcome a wide array of marine live. Great overhangs and small caves covered with soft corals combined with it's crystal clear water are one of the main reason for wide-angle photographer's to visit this site. Napoleon Wrasse and big Green Turtles often visit this area. It is also a good place to find Purple Dart and Sailfin Gobies.
Lekuan 3
One of Bunaken Best dive sites, as it starts with a nice sandy slope with underwater pinnacles and continues to a wall, which drops to over 200m. Groups of Jacks and Barracudas are often found. Not to miss the small creatures that are resident to this site too, like cleaner shrimps, a nice variety of Nudibranchs and Flatworms to name a few. Gorgonians and big sponges decorate the wall in a magnificent way and complete it with a huge range of colorful fishes.
Celah - Celah (Cracks)
This site offers a deep wall with large cracks everywhere. A great site especially with a bright sunlight passing through and brightens up the blue water. It is one of the favorite areas for photographers, due to its "lunar" landscape.
Mandolin
...tops out near the surface, with a wall that is alive with fishes such as fusiliers, surgeon fish, unicorn fish and bannerfish. Mandolin is named after the same traditional musical instrument due to its shape from a bird's eye view. Small schools of Reef Fish, Angelfish, Bumphead Parrotfish and Gobies are there for your enjoyment. Not to forget the groups of large sized Barracudas, together with different colors and types of sea fans. In the deeper part, there is possibility to see Blacktip Reef Sharks.
Bunaken Timur
This area of Bunaken is always protected from the big thunderstorms of the bad season, and it permits an unusual growth of many species of hard and soft corals. This is the point with the highest coral biodiversity all around the area. Spectacular also for snorkeling, if you are lucky can spot also turtles and eagle rays swimming in the blue.
Mike's Point
Located on the north west of Bunaken Island, this site was named after well-known underwater photographer, Mike Severns. A wall covered with a great variety of different, colorful corals is a home for a huge range of tropical reef fish, which makes it perfect for fish portrait photography. Big fishes are common guests to this site too, as it often has a strong current that is affected by the tides. The reef floor is covered in different types of Sponges that make it a great area for deeper diving.
Muka Kampung
It is located exactly in front of the village of Bunaken. Strong current are prevailing in the area caused mostly by the location of the site. However, it is an interesting drift dive to cover a lot of area. Numbers of large Sea Turtles are common residents here. The site itself is well decorated with hard and soft corals along the wall with some overhangs and crevices where the small critters will draw your attention. School of Jacks and Barracudas can easily to be found as well as humphead parrotfish, napoleon wrasse and big Dogtooth tunas patrolling along the reef. The top of the reef is a perfect place for the safety stop, with depth around 4-5 meters.
Aluang Banua
This site has excellent macro objects to offer. One thing for sure is that you have to pay attention on the disguised creatures. Leaf fish, Ghost pipefish to name a few creatures, which have been seen here. The wall also offers beautiful caves, which often became a sleeping place for white tip reef shark. Sea Turtles and Eagle Rays are something that you may also see.
Fukui Point
Located on the southwest side of Bunaken. Named after a Japanese dive instructor who first described the site in the 1980's, Sandy slopes leading to patches of hard and soft corals. This is one of the dive spots around Bunaken Island with no deep wall reef. Going down to around 15 meters only, there are 3 Giant Clams that are placed in a row, always surrounded by loads of Butterflyfish that are not shy to approach divers.
Raymond's Point
South from Mike's Point lays a beautiful wall covered in sponges, with hard and soft corals. The rich environment of the wall has its own charm. This site also has a large cave and due to the strong currents often present, is the Bunaken site richest in Wire corals.

Ron's Point
A sandy slope site with occasional visitors such as Tuna, Jacks, Barracudas and not to forget Whitetip Reef Sharks and even occasional sightings of Gray Reef Sharks occur. The coral covered reef is not to be missed and observed as you can find Ghost Pipe Fish, Leaf Fish and also different type of anemone and Clown Fishes.
Sachiko's Point
A very steep Reef decorated with amazing soft and hard corals in the shallower areas of the reef. It is a vertical wall on the northeast side of Bunaken, with visibility frequently in the 30 to 40-meter range. In midwater, away from the reef, there are literally thousands and thousands of schooling red tooth Triggerfish. Large Gorgonians can also be found in the area. The slight current here means larger pelagics such as sharks, turtles, barracuda, and Napoleon wrasse, frequent the area other critters typically found here include moray eels, sea snakes, leaf scorpionfish, nudibranchs, crabs and shrimp.
Siladen Island,Siladen Point
Siladen Island is a small island surrounded by a beautiful white sandy beach. The southern side of Siladen Island, Siladen has a vertical wall in large steps. The reef top is spectacular with a huge variety of hard & soft corals, and it is therefore an excellent spot for snorkeling. The colors of the corals here are just amazing - it is always amazing to find up to 10 different-coloured feather stars attached to a single large sponge. the sandy bottom offers lots of tiny creatures to be observed. White tip Reef Sharks are regular visitors as current is often present on this site.
Manado Tua Island
The dive sites around Manado Tua have steep vertical winding walls with many cracks, canyons and small caves. You can enjoy beautiful hard and soft corals, reef fishes, turtles and reef sharks.
Panggulingan
Located in the Eastern part of Manado Tua Island, This site starts off with a slope going down to 30m and then continues to a vertical wall with a large reef flat rising to about 5m. Large Schools of big sized Barracudas, Batfish Napoleon Wrasse, schooling Banner fish and Butterfly fish can easily be found in this area. There are quite strong prevailing currents on this site, which make it a good place to see Sharks and Spotted Eagle Rays.
Muka Gereja (Church Front)
The site is exactly in front of a Manado Tua Church. The waters around Muka Gereja are generally calm and offer excellent visibility with moderate to strong currents. It features an interesting, beautifully covered wall, with big barrel sponges, some of them almost 1 meter in diameter. The fascinating thing about this dive site is not only about what it has to offer underwater; the great volcano is an amazing sight when you surface. Another "fish Dive" - a real aquarium!
Negeri (Country)
The site is situated towards the east of Muka Gereja. Currents are very much depending on the direction and strength of the wind. With the same great visibility, there is the possibility to see Silvertip Sharks, on its sandy slopes around the 30 m mark. Around the wall, which is decorated with a huge variety of beautiful soft corals, resident habitants like the Banded Pipe Fish, Angelfish and other Schooling fish are almost certain to be seen.
Manado Coast and Manado Bay
Tanjung Pisok
The dive site on the coast of the mainland which is called Tanjung Pisok has a reef flat sloping to 15-20 meters depth, and is very rich with large tabular sponges, reef fishes, nudibranchs, ribbon eels and unusual green tree corals.Molas Shipwreck
There is also a diveable wreck, the Japanese Cargo named Molas, which from what we can discern, takes its name from the village of Molas, on the more Northern side of Manado. The history books are not too clear about its fate, but we again have good reason to believe it was torpedoed around 1942. Sitting upright starting around 10m the propeller sits at 40m. Although not safe for penetration, remember to bring your dive light. You can opt to "sit out" the wreck and explore a reef close by instead.

Batu Hitam (Black Rock)
This site is the continuation of the Molas wreck reef slope in an easterly direction. It is a gentle dive with hardly any currents and great for macro lovers. The reef consists of a sandy slope with coral patches and finishes off as a little wall. Great for critters like ribbon eels, rare nudibranchs, leaf fish and frogfish, crocodile flatheads and such. It is a perfect dive to do in combination with the Molas wreck.

City Extra
Located exactly in front of a well-know seafood restaurant, this sandy area offers tons of critters to be spotted. Ghost pipefish, mimic octopus, Ambon Scorpionfish, Seahorses, Boxfishes, Flamboyant cuttlefish just to say some. And if you are lucky, this is the right place to see the Dugong.

BMJ
When you will go down in this site, the first impression would be something like "where the hell am I??"... Site directly exposed to bad season storms, present a lot of broken coral and rubble areas. However, it's a paradise for nudibranchs and many other critters like ghost pipefish, boxer crabs, mantis shrimp and many more.(source: tasikria.com)

Mantehage Island,the Other Side of Bunaken Island Natisional Park Area.



Mantehage Island,Other sides of Bunaken island Marine nasional park

Bunaken National Park extends over an area of 890.65 km² of which only 3% is terrestrial, including Bunaken Island, as well as the islands of Manado Tua, Mantehage, Nain and Siladen,The waters of Bunaken National Marine Park are up to 1,566 m deep in Manado Bay, with temperatures ranging between 27 to 29 °C. It has a high diversity of - corals, fish, echinoderms or sponges. Notably, 7 of the 8 species of giant clams that occur in the world, occur in Bunaken. It also claims to have seven times more genera of coral than Hawaii, and has more than 70% of all the known fish species of the Indo-Western Pacific.

Oceanic currents may explain, in part, why Bunaken National Marine Park has such a high level of biodiversity. Northeasternly currents generally sweep through the park but abundant counter currents and gyros related to lunar cycles are believed to be a trap for free swimming larvae. This is particularly true on the south side of the crescent-shaped Bunaken Island, lying in the heart of the park. A snorkeler or diver in the vicinity of Lekuan or Fukui may spot over 33 species of butterfly fish and numerous types of groupers, damsels, wrasses and gobies. The gobies, smallish fish with bulging eyes and modified fins that allow them to attach to hard surfaces, are the most diverse but least known group of fish in the park.

Based on Geology, North Sulawesi is considered to be a 'young' formation, of 5-24 million years of age. The region has undergone explosive volcanism 1.5-5 million years ago, which resulted in the volcanic tuff that characterizes the existing topography. Manado Tua is an inactive volcano formed in a classical cone shape and rising over 600 m above sea level, the highest elevation in the park. Bunaken Island also has volcanic origins with a significant amount of uplifted fossil coral. Nain Island is also a dome-shaped island, 139m in height. Mantehage Island is relatively flat and seems to be sinking into the sea. The island has extensive mangrove forest flats, partially separated by saltwater channels. Siladen is a low-lying coral sand island with no significant topography. Arakan-Wawontulap and Molas-Wori on the mainland of North Sulawesi are relatively flat areas at the base of volcanic hills. The absence of a continental shelf allows the coastal area of the park to drop directly down the continental slope. The sea depth between the islands of the park is 200 to 1,840 metres.(source: northsulawesi-tourism).


Nain Island,Bunaken Island Nasional Marine Park Area





Nain Island,Bunaken Island Nasional Marine park Area.
Location: Off the northeastern coast of Montehage,Normal most island from Bunaken.
Access: 100 min by dive boat from most dive resorts.
Conditions: Very strong current
Average depth: 30m
Maximum depth: 80m
Nain Island is the northernmost island in the Bunaken National Marine Park and has about 3 dive spots near it. This site is strictly for experienced/technical divers only. The interesting part begins only below the 40m level and caves are located beyond 60m depth. Furthermore, these dive sites are far from help in mainland. Dive guides from the resorts are often reluctant to bring divers to this site because of the dangers involved.
Having said that, the risk is often rewarded by rare sights of hammerhead sharks, huge tuna, dolphins and pilot whales.
Nain Island is one of the islands in the site of Bunaken Marine Park. Just like any other islands such as Siladen, Mantehage, Manado Tua and Bunaken, the island has an amazing panorama. It is not only the panorama which attracts tourists to visit the island but also its biodiversity. You can find various species of fish and sea creatures in the island. The island has incredible topography of both the sea and the land. Hence, when you visit the island, it’s not only marine activities you can do but also activities on land. You will have an exciting experience when visiting the island, especially when your best friends or family accompany your travel to the island.Nain Island is located off the northeastern coast of Montehage Island, North Sulawesi, Indonesia. The most northern island in the Bunaken Marine Park Site is Montehage. Hence, Nain is near the northern part of the Bunaken Marine Park Site. To reach the island, you can start from Manado. From wherever you are, you can fly to Manado first. Then you can travel by boat or charter a private boat to Nain Island. You better prepare yourself when visiting the island. You should prepare equipment to do your activity and enough food. The island is not as popular as Bunaken or Siladen. Thus, it is quite more difficult to find comfortable accommodations in this island.
Activities
When you come to Nain Island, you can do marine activities. The most interesting marine activity is diving. The current of the sea in this island is very strong. While, the average depth of the sea is 30 m and the maximum depth is 80 m. Such depth and current are suitable for professional divers. If you are an amateur diver, you should not dive alone. You should take a guide with you. Ask him or her to lead your diving activity. While diving, you can record the beautiful fish and other creatures swimming around you. There are some prominent species such as barracudas or groupers. If you are lucky, you can find more unique species like hammerheads and jack fish. They are lovely species. Record the fish when they swim or line in its schools. The record will become the most amazing video from your marine adventure in this island.
Accommodations
It is better for you to plan your accommodations first before you go to Nain Island. The island doesn’t have facilities as complete as popular islands like Bunaken or Siladen. Hence, you can plan to stay in one of the islands. Otherwise, you can stay in one of the local people’s houses in the island.
