Rhabdopleurida

Rhabdopleurida is one of three orders in the class Pterobranchia, which are small, worm-shaped animals. Members belong to the hemichordates.^[1][2] Species in this order are sessile, colonial, living in clear water and secrete tubes called coenecium. Rhabdopleura is the best studied pterobranchs in developmental biology.^[3] Some claim Rhabdopleura is an extant graptolite.^{[4] [5]}

Taxonomy

This small order is monotypic. It has only a single genus, containing four to six species.
