Brown
sea cucumber
Bohadschia vitiensis*
Family Holothuriidae
updated
Feb 2020
Where
seen? This sea cucumber is sometimes seen on Cyrene Reef
among the seagrasses. Elsewhere, it is found in shallow sheltered lagoons on sand and sometimes among rubble and coral patches. It is said to remain buried
in sand during the day and only emerges at dusk. It can crawl quite rapidly over the surface, for a sea cucumber. Some consider Bohadschia similis and Bohadschia vitiensis to be the same.
Features: 15-30cm long. Body oval,
uniformly coloured with distinct upper and underside. Colours variable: may be orange, yellow, brown, pink. Underside flat, pale. Tube feet tiny dark with pointed tips, emerging from dark spots evenly scattered all over the body including underside. Underside flat pale. Mouth facing downwards with 20 short feeding tentacles, yellowish with bushy tips. When disturbed, it
readily releases from its backside, large sticky white cylindrical tubes called Cuvierian tubules.
Babie cucumbers: It is recorded to reproduce annually in various parts of the world. Juveniles appear similar to small adults.
Human uses: It is sometimes harvested
together with other edible sea cucumbers, by hand collecting and free diving, sometimes using lead bombs. But the Cuvierian tubules
make them 'disagreeable' and they do not have a high commercial value. It is considered a delicacy by Asians. It is also an important protein component in traditional diets of island communities or eaten in times of hardship. |
