Donkey Dung Sea Cucumber (Holothuria mexicana)

Also known as Black Sea Cucumber, Dung Sea Cucumber, Lollyfish, Tripang


Also known as Black Sea Cucumber, Dung Sea Cucumber, Lollyfish, Tripang.

Found singly or in pairs, over muddy sand, and in seagrass beds, sometimes close to mangroves, of shallow coastal reefs and off-shore reefs.
They feed on algae and tiny zooplankton.
Length - 50cm
Depth - 0-20m
Widespread North Atlantic - Azores, Western Central Atlantic, Caribbean

Some sea cucumbers crawl around on the bottom slowly filtering sand through their tentacles to gather food, while others spread their tentacles above them to capture plankton. A number of sea cucumbers feed nocturnally while others feed by day.
There are sea cucumbers that hardly move while others are more active often perching on tall sponges to feed.
Sea cucumbers often attract hitch-hikers like shrimps and crabs that crawl over their skin, also pearlfish that enter via their anus.
As a means of defence sea cucumbers can expel their intestines or respiratory organs in the form of sticky threads, but these can quickly regenerate.
Juveniles often mimic sea slugs.
Some types of sea cucumbers are edible and considered a delicacy in the Far East countries. Ref:

    Thank you for your information about the Sea Cucumber. We are located in the Bahamas and have a host of The Donkey Dung Sea Cucumber (aka to us as the sea cock). My inquiry wishes to ask whether Crawfish (Panularius Argus) or the Spiny Lobster eat these sea cucumber? Some say that they always see plenty of these near lobster traps. Can you comment on this topic.?
