The Crustacean family includes crabs, lobsters and shrimp. Arrow Crab Carry Crab Harlequin Crab Hermit Crab Orangutan Crab Porcelain Anemone Crab Zebra Crab 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. Close Arrow Crab Also called: yellowline arrow crab. Scientific name: Stenorhynchus seticornis The very spider-like little guys are almost always found hiding around anemones. Close Harlequin Crab Scientific name: Lissocarcinus laevis These small spotted crabs live at the base of stalk anemones. Close 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. Close 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> Close Zebra Crab Scientific name: Zebrida adamsii These little black and white critters are found almost exclusively riding around on fire urchins. Close 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. Close
