Hofsteniidae Explained

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
