Orange sea cucumber
Mensamaria intercedens*
Family Cucumariidae
updated Oct 2016
Where seen? This blue-orange sea cucumber is sometimes seen on our Northern shores, usually attached to coral rubble, often near sponges, sometimes partially covered by sediments, nestled up among hydroids, draped with synaptid sea cucumbers or smaller sea cucumbers. In Australia, they are found on intertidal shores in 'U-shaped' burrows or entwined in rhizomes of seagrasses.

Features: 8-12cm long. Body spindle-shaped (pointed at both ends) and rather angular with long thin tube feet in rows along the length. Actually dark blue body with orange tube feet from orange stripes along its body. But sometimes the orange stripes are wide so that it appears mostly orange with fainter dark blue stripes. Its feeding tentacles are white with black spots and with pinkish or pale orange branches.
