Common name: Sea Cucumbers

Holothuriidae, commonly known as sea cucumbers, are echinoderms from the class Holothuroidea. They are leathery, elongated animals found on the sea floor worldwide. Many are harvested for human consumption. In the aquarium, they play a role in the cleanup crew, consuming detritus and aerating the sand bed. Some species can be sensitive to changes in water quality and may release toxins when stressed, so careful selection and acclimation are crucial for a successful introduction to a reef tank.
