Aplacophora
mollusk class
Quick Summary
Aplacophora is a class of mollusks characterized by their worm-like bodies, which lack shells. These marine mollusks are typically found in deep water and are believed to represent either a primitive molluscan form or a reduction from more advanced, shelled ancestors. There are approximately 300 known species within this class, divided into two subclasses: Chaetodermomorpha (Caudofoveata) and Neomeniomorpha (Solenogasters). Caudofoveates burrow in sediments and consume microorganisms, while solenogasters prey on cnidarians.123
