Let's do Some Zoology!

Sipunculus nudus

…is a species of sipunculid (peanut) worm native to subtidal zones and seabeds worldwide. Like most peanut worms S. nudus lives most of its life in a self-made sand burrow where it sits and feeds on any organic material that passes by its burrow. Like certain sea cucumbers S.nudus only exposes its fragile tentacles to feed at night, and mostly works on its burrow during the day. S. nudus is considered a delicacy and is commonly sold throughout southeast Asia.
