updated Oct 2019

Where seen? This large long smooth sea cucumber with dark markings is sometimes seen buried near seagrasses on some of our shores. Those seen were buried in the sand near the low water mark, with only a tip of the body sticking out. Elsewhere, it prefers lagoons and seagrass meadows with sandy ground.

Features: 10-12cm long. Body cylindrical and sausage-like, tapering at the anus. Mostly pale or white with irregular darker blotches, about 8-10 blotches in 2 rows. It has an obvious underside which is paler with fewer dark markings. The tube feet seem small and stumpy. It appears to have a small mouth with 20 tiny yellow feeding tentacles. Colours seen include pale white with darker or brown markings, orange to yellow with darker markings. It can secrete short white Cuvierian tubules when disturbed, but usually doesn't do so.

Human uses:
It is among the sea cucumbers harvested for food in Madagascar.
