Acorn worm: Anatomy, Reproduction & Overview

The acorn worms or Enteropneusta are a hemichordate class of invertebrates. The closest non-hemichordate relatives of the Enteropneusta are the echinoderms. There are 111 known species of acorn worm in the world, the main species for research being Saccoglossus kowalevskii. Two families—Harrimaniidae and Ptychoderidae—separated at least 370 million years…
