Characteristics
Sea cucumbers browse slowly over the bottom, feeding on microorganisms associated with sediment particles. Then, like earthworms, they pass out strings of undigestible material such as sand grains and shell fragments.
Adult sea cucumbers have few known predators, with the exception of three species of sea stars. These predators can induce a violent arching back-and-forth escape response in sea cucumbers, which is the only time they move rapidly! Juveniles are probably more vulnerable and this may explain their secretive behaviour.
Range: Indo-Pacific and Eastern Pacific.
