Armoured sea cucumber
Psolidium sp.*
Family Psolidae
updated Dec 15

Where seen? This small sea cucumber is seen stuck very firmly onto rocks in dark places.

Features: About 1cm long, the upper side of the body is covered with hard calcareous plates. Body very hard, sausage shaped with a very flat base (creeping sole). Much like a limpet, it clamps tightly onto a hard surface with several rows of tiny tube feet. Mouth and anus facing upwards on conical protrusions. When submerged, short bushy feeding tentacles emerge from the mouth and tiny tube feet emerge all over the body.

Sometimes mistaken for a tiny colony of hard corals or a hard ascidian.
