Echinodermata, Class Holothuroidea

Sea Cucumbers

Sea cucumbers feed upon detritus collected from the seafloor or suspended in the water column.  They are more active at night and often host crustaceans, mollusks, or fish within and without.  They move and attach themselves to the substrate using tube feet.  Many species eject sticky white threads called Cuvierian Tubules when disturbed.  These parts along with any internal organs are regenerated.  The generic Hawaiian name is loli., Japanese is namako.
