Cenderawasih, wrecks and reefs.

Located in the eastern fringe of the Indonesian archipelago, is Cenderawasih Bay. This is about as remote as it gets.

Cenderawasih Bay

Cenderawasih Bay is well known for it’s whale-sharks, but, it also has some of the best dive spots in the world. Floating weightlessly you pass by, hard corals,

and lettuce corals, amongst others.

This isolation has consecrated Cenderawasih as an ancient sea, and it has a high percentage of endemic fish and coral species found nowhere else in the world.

The bay holds substantial clues to the geological history and tectonic evolution of the region. Research has established that until recent times it was geologically isolated from the flow of Pacific tides.

Ichthyologist Dr Gerald Allen has hailed the bay as “the Galapagos of the East”, basing this claim on documented findings of an “evolutionary cauldron” of new and unique coral, shrimp and fish species. Extensive surveys documented 995 species of fish and more than 500 species of coral.

The many large barrel sponges, as well as other corals,  are all in a pristine condition, probably due to the remoteness and natural protection of the bay.

Barrel Sponge

Along the drop off’s, in a water temperature of 29 degrees centigrade, are many kinds of whip corals, sponges and giant sea fans. Most of the time we had a visibility in excess of 30 meters.

Sea Fan

There is a seemingly endless variety of sea fans, as well as hard and soft corals. Drifting around with a camera is so frustrating. It’s almost like a kid in a candy store. There are too many beautiful things. You just can’t photograph everything. The whole place is so photogenic.

The WW11 wrecks at Manokwari are considered to be one of the best wreck diving sites in the world.

Wreck of landing craft

Gliding amongst the wrecks, in fairly shallow water, you soon become enveloped and in one large school of fish after another……….. and this is all happening in what could be a garden nursery.

You are constantly enveloped by large schools of Sweetlip Emperors and  Yellowtail Snappers (Ocyurus chrysurus)

When you turn your back, a large school of yellow blue fusiliers, that’s always in a hurry, come sweeping by.

The synchronous movement of small fish, mimicking the ever changing shape of clouds, is poetry in motion. They are commonly found under the jetties.

Every so often, a school of barracuda come gliding past.

There are so many different types of anemone all around every dive site.

The nimble Venus anemone shrimp or “glass shrimp” that float around, between and over the anemone tentacles can grow up to a maximum size of about 3 cm. They are perfectly formed, transparent, blue tinged creatures. It’s difficult not to just sit and watch them for a whole hour.

Anemone fish are always fascinating to watch. This Pink anemone-fish (Amphiprion perideraion) was constantly darting in and out between the anemone tentacles.

A Two-bar Anemone-fish  (Amphiprion bicinctus) is also briefly inspecting life outside of the anemone.

Another Clown Anemone-fish (Amphiprion percula) enters and exits the scene briefly. It can also be a Common clownfish, or better known as “Nemo“(Amphiprion ocellaris)  in the Walt Disney film ‘Finding Nemo’,

Never a dull moment, with the bizarre swimming style of the  razorfish (Aeoliscus strigatus).

It’s always great to see a colourful mantis shrimp. It has one of the most elaborate visual systems ever discovered.

This one looks like a (Penaeus monodon) or a  giant tiger prawn.

Banded Coral Shrimps (Stenopus hispidus) are also known as “Boxing shrimps”   due to this otherwise peaceful shrimp’s aggressive behaviour towards other Banded shrimps. It can move freely between obstacles, without it’s long antennae touching anything.

Banded Coral Shrimps (Stenopus hispidus)

Tiny anemone shrimps (Periclimenes brevicarpalis) almost look artificial with their white spotted tails and transparent glass like bodies. If it wasn’t for the few coloured spots on their bodies,           they would have been completely invisible.

Sexy Anemone Shrimps (Thor amboinensis) are everywhere.

Arrow crabs (Hyastenus bispinosus ) are about 2cm in size and very well camouflaged. It walks along the bottom and looks just like a praying mantis.

This hermit crab was inquisitive and came over to have a look at what I was doing.

When this Anemone Hermit Crab (Dardanus pedunculatus) outgrows it’s shell, it will be discarded and all the anemone on the old shell, will also be transferred to the new shell.

Tiny Hermit Crabs (Pagurixus rubrovittatus) grow up to 0.5mm in size. This one was feasting on the even smaller krill that were attracted by my strobe lights.

This White-spotted Left-handed Hermit Crab (Dardanus megistos) almost seems to be too big for its shell house.

Porcelain crabs are tiny and extremely busy, usually with a body width of less than 15 millimeters.  Not a fraction of a second goes by that they aren’t busy doing something.

Strange creatures seen on “muck” dives in Cenderawasih.

Muck diving gets its name from the type of environment at the bottom of the dive sites.

DSC06399-802

Under a jetty

 

It is frequently muddy, silty, sandy or old volcanic ash, as well as areas with lots of vegetation and other man made rubbish.  You often see bizarre and unusual creatures on such dives.

Muck diving in Cenderawasih Bay turned out to be quite a pleasant surprise.

Especially under a jetty, there are many strange, creatures swimming and crawling around. Really a worthwhile experience

Upside-down jellyfish (Cassiopea andromeda)

The Upside-down jellyfish (Cassiopea andromeda) is a true jellyfish. The medusa lies upside down on the bottom and from there it’s name. It has a mild sting from stinging cells that are secreted in a mucus layer that covers the jellyfish when it feels threatened.The colours can vary quite a bit depending on the location. It’s about the size of a man’s hand.

On the video it can be seen that some discarded plastic-can turned out to be quite a popular place with fish that were moving in and out constantly.

DSC06240-600

White-spotted Left-handed Hermit Crabs (Dardanus megistos)

The White-spotted Left-handed Hermit Crabs (Dardanus megistos) are quite interesting to watch. They can move around very fast.
The Anemone Hermit Crab (Dardanus pedunculatus), on he video, is carrying four anemones on its shell and they will be transferred onto the new bigger, shell, once the crab has outgrown this one.

DSC05754-147

Tiny Hermit Crab (Pagurixus rubrovittatus)

This Tiny Hermit Crab (Pagurixus rubrovittatus) is very small, especially if you compare it to the snail next to it. My video lights were attracting thousands of Krill. This little Hermit Crab couldn’t believe his luck and couldn’t eat all the food fast enough that was coming his way. He was having an absolute feast.
The Tail-spot Squirrelfish (Sargocentron cornutum) is very common.

Honeycomb Worms (Sabellariidae lygdamis)

The Honeycomb Worms (Sabellariidae lygdamis) are very difficult to photograph. They disappear underground, extremely fast, whenever they detect the slightest movement.

DSC06244-604

Half-spined Seahorse (Hippocampus semispinosus)

The Half-spined Seahorse (Hippocampus semispinosus) seems to float around and go with the flow. It will curl its tail around a leaf or branch once it reaches a suitable spot where it wishes to stay. It is also one of the suction feeders.

DSC06293-653

Praying-Mantis Shrimp (undescribed)

This Praying-Mantis Shrimp (undescribed), so named by myself,  is a very unusual looking shrimp. It is covered in camouflage and looks exactly like a Praying Mantis walking around on the sand. It might be a  Hyastenus bispinosus (Arrow crab).

DSC06301-661

Devilfish (Inimictus didactylus)

The Devilfish (Inimictus didactylus) is part of the larger Scorpionfish group. It is extremely ugly and crawls around on the sandy bottom.

DSC06316-676

Long-Tailed Sea Hare (Stylocheilus spp)

Even the Long-Tailed Sea Hare (Stylocheilus spp) and Nudibranchs are fairly colourless to blend in with the “muck” as part of their camouflage.

DSC05723-124

Pygmy Octopus

The little Pygmy Octopus with it’s rectangular eyes is very cute to watch as it jogs along the sandy bottom.
