Yellow Sea Sand Cucumber - Holothuria sp.

Class: Holothuroidea

Sub-Class: Aspidochirotacea

Species: Holothuria sp.

This is a Holothuria sp. sand eating cucumber. It uses its feather appendages around the mouth to find appropriately sized food particles on the substrate. This mode of feeding is called deposit feeding.

This specimen is about eight inches in size.

This is a pretty rare event of a sea cucumber doing sexual reproduction… it is much more common for them to multiply via asexual reproduction method where fission occurs along the anterior-posterior axis of the body (it split’s in two).

This event happened after the tank lights had already turned off for the night.
