Lauridromia intermedia is a species of crab in the family Dromiidae and is native to the western Indo-Pacific. It often carries a piece of sponge on its back by way of camouflage, and one individual was found carrying a sea anemone in a similar manner.

Description

Lauridromia intermedia is a small crab with a maximum

legs are much longer than the fourth and fifth. These latter have three or four spines on the dactylus, two or three small ones and a single opposable large one. The carapace is orangish or yellowish-brown with a small dark red patch near the front. The tips of the chelipeds are pink.[2]

Distribution

Lauridromia intermedia is found in shallow water in the western Indo-Pacific. Its range includes the East African coast,[3] Madagascar, the Seychelles,[1] Australia, New Caledonia, the Philippines, Japan and Taiwan. Its depth range is 7 to 150 m (23 to 492 ft) but it is seldom found deeper than 40 m (131 ft).[2]

Ecology

Crabs in the family Dromiidae are often known as "sponge crabs" due to their habit of carrying bits of sponge on their carapace, clipping them to size and shape.[4] Sometimes instead they carry colonial ascidians and occasionally other objects. Lauridromia intermedia usually carries a piece of sponge, holding it in place with the claw-like spines on the end of its fourth and fifth pairs of legs.[3]
