SEA Undersea

The Crustacean family includes crabs, lobsters and shrimp.

Carry Crab

Also called: urchin crab.

Scientific name: Dorippe frascone

It's very suprising seeing a sea urchin moving quickly along the sandy bottom. On closer inspection, you'll see that the urchin is being carried around by a crab, a species specifically adapted to the purpose, distinct from decorator crabs.

Arrow Crab

Also called: yellowline arrow crab.

Scientific name: Stenorhynchus seticornis

The very spider-like little guys are almost always found hiding around anemones.

Harlequin Crab

Scientific name: Lissocarcinus laevis

These small spotted crabs live at the base of stalk anemones.

Hermit Crabs

Scientific name: Superfamily Paguroidea

There are over 500 individual species of hermit crabs, so telling one from the other when they're in their shell is a bit difficult.

Porcelain Anemone Crab

Scientific name: Neopetrolisthes maculosus

These crabs seem to be easier to find a night, when they come out on top of their anemone hosts. By day they usually hide under the anemone./p>

Zebra Crab

Scientific name: Zebrida adamsii

These little black and white critters are found almost exclusively riding around on fire urchins.

Orangutan Crab

Scientific name: Achaeus japonicus

With its long legs and “hairy” red color, the common name of this crab seems like a good fit. We saw a large number of these around Bangka island and the Lembeh strait. They're commonly found, as pictured, on bubble coral.
