Hofsteniidae is a family of acoels. This family contains seven species in three genera. [1]
This worm ranges in size from 100 μm for embryos to 500 μm for adults, and exhibits "whole-body regeneration" capability, where entire body parts regenerate when removed from the body.[2] They have a simple nervous system and a bowel sac with no way out.[3]
Genera
There are three genera in the family Hofsteniidae.[1]
Hofstenia Bock, 1923
Hofsteniola Papi, 1957
Marcusiola Steinböck, 1966

There are seven species in the family Hofsteniidae.[1]
