2. HemichordataHemichordata is a phylum of marine deuterostome animals, generally considered the sister group of the echinoderms. They date back to the Lower or Middle Cambrian and include two main classes: Enteropneusta (acorn worms), and Pterobranchia. A third class, Planctosphaeroidea, is known only from the larva of a single species. The extinct class Graptolithina is closely related to the pterobranchs. Acorn worms are solitary worm-shaped organisms.
