It inhabits shallow waters, in a wide variety of bottoms (sand, mud, rock, seaweeds...).[1]

Reproduction

Similar to other tropical Holothuroidea, the Isostichopus badiontus is dioecious. Males and females release their gametes into water where fertilization happens externally. A study in the Caribbean Sea observed that the species has an increase in reproductive activity when temperatures increase.[3]

Conservation status

As bottom feeders, Isostichopus badionotus individuals are threatened by contaminated substrates due to metals left behind by boats.[4] Additionally, they are popular in Asian cuisine, and are also threatened by illegal fishing and trafficking.[5] [6]
