Aplacophora is a group of mollusks without shells, typically found in the deep sea. They have a cylindrical body, with a head and a tail, and are covered in spines. They range in size from 0.2 to 2.5 cm in length. Aplacophora inhabit the deep sea, from the abyssal plain to the continental shelf. They have a lifespan of up to 10 years. The current population of Aplacophora is unknown.
Name Origin: The name Aplacophora is derived from the Greek words aplax, meaning "shield," and pherein, meaning "to bear." This is in reference to the fact that members of this group of mollusks have a shell composed of a series of overlapping plates, which gives them a shield-like appearance.
