Speckled Sea Cucumber, Actinopyga mauritiana

Pu'uhonua O Honaunau National Historical Park
Sea cucumbers live in marine sediments which they ingest in order to digest the organic nutrients and small organisms therein. Many sea cucumbers can eject their entire digestive tract when threatened by a predator. This distracts the predator while the rest of the sea cucumber makes its getaway.
