seen? This small sea cucumber is seen stuck very firmly
onto rocks in dark places, so far at Changi and Pulau Ubin.
Features: About 1cm long. Body oval with distinct flat underside. Upperside covered with hard calcareous plates. Colours light maroon, bright orange, brown. Much like a limpet,
it clamps tightly onto a hard surface with several rows of tiny tube
feet on the underside. Mouth and anus facing upwards on conical protrusions. When submerged,
short 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.
