Orangutan Crab are only tiny little crabs with live amongst soft coral on the reefs of Bunaken National Marine Park.
They may be tiny and very hard to photograph but they are some of the most beautiful marine creatures found in the Bunaken Marine Park.
You have to have a sharp eye as the Orangutan Crab only grow to around 2 centimeters long, though their bright orange colour make them fairly easy to spot against the white soft bubble coral that they like to live on.
The first time you see an Orangutan Crab you will see exactly where they get their name. Named after the big hairy Orangutan that live in the jungles of Sumatra and Borneo. The Orangutan Crab look like they are hairy with bright orange colour.
One of the best places to see the Orangutan Crab in the Bunaken National Marine Park is at the dive site called Lekuan II which is a vertical wall dive off the coast of Bunaken Island. Here you should be able to spot several of the Orangutan Crab at around 15 - 18 meters depth.
Orangutan Crab are part of the Inachidae family (same as the spider crab) and are found not only in the Bunaken Marine Park but all through the Indo-Pacific region. They live primarily in tropical waters close to the equator.
