Achaeus spinosus is a small decapod which belongs to the large family of the Inachidae or the spider crabs.
Description
The Achaeus spinosus carapace has an oval shape and does not exceed Шаблон:Convert in length. This crab possesses long fine clawless legs, except the front pair which is smaller and bears chelae (pincers). The pedunculate eyes are red.[1] The whole whitish body is thickly covered with fine hairs which help to fix some pieces of sponge or fixed hydroids for camouflage.[2]
Distribution and ecology
Achaeus spinosus can be observed in the tropical waters of the Indo-west Pacific area, including the Red Sea.[3] Achaeus spinosus usually lives in association with some species of soft coral or sponge.[2]
Achaeus spinosus feeds on plankton and suspended particles which it catches by climbing on the host with whom it's in association to expose itself to the current.[4] Achaeus spinosus is often observed on its living support. This crab is mainly active at night.
