This marine crustacean is commonly known as the “Pink hairy squat lobster”, also known as the “Fairy crab”. Its scientific name is Lauriea siagiani. Actually, L. siagiani is not really a lobster, but belongs to a group of crabs called Anomurans.
Anomurans are decapod crustaceans, meaning they have ten appendages (legs). But unlike their relatives called brachyuran (the true crabs), the two rear appendages are small and are hidden under the shell, together with the respiratory organs or gills.
The fairy crabs are tiny. Adults typically measure no more than 1.5 centimetres; thus they are of no value from the point of view of a commercial fishery. However, despite their small size, and because of it, they are spectacularly beautiful. Their body is almost translucent; their legs show edges of intense, nearly florescent pinkish-purple color, with purple spots and lots of white hairs covering the entire body.
Anomuran crustaceans live in almost all oceans, but this particular species, the fairy crab, lives associated with a species of sea sponge called the “Giant barrel sponge” (Xestospongia testudinaria) which abounds in coral and rocky reefs off the coast of the Lesser Sunda Islands (Bali) and Sulawesi, Indonesia.
Fairy crabs are usually difficult to photograph because they are very shy and hide under the projections on the sides of the sponges.
