Rhabdopleura
''Rhabdopleura'' is a genus of colonial sessile hemichordates belonging to the Pterobranchia class. As one of the oldest living genera with a fossil record dating back to the Middle Cambrian, it is also considered to be the only living genus of graptolites. ''Rhabdopleura'' is the best studied pterobranch in developmental biology. Research in the 2010s by Jörg Maletz and other paleontologists and biologists have demonstrated that ''Rhabdopleura'' is an extant graptolite. Species List of species from Maletz (2014): ;Living species The genus ''Rhabdopleura'' contains at least five living species. * ''Rhabdopleura annulata'' Norman 1921 — Indo-Pacific region * '' Rhabdopleura compacta'' Hincks 1880 — Atlantic * ''Rhabdopleura normani'' Allmann, 1869 — Atlantic and parts of the Pacific * ''Rhabdopleura recondita'' Beli, Cameron and Piraino, 2018 — Mediterranean * ''Rhabdopleura striata'' Schepotieff 1909 — Pacific (Sri Lanka) ;''Nomen dubium'' (doubtful) * ''Rhabdopleu ...

Rhabdopleuridae
Rhabdopleurida is one of three orders in the class Pterobranchia, which are small, worm-shaped animals, are the only surviving graptolites. Members belong to the hemichordates. Species in this order are sessile, colonial, connected with a stolon, living in clear water and secrete tubes called tubarium. They have a single gonad, the gill slits are absent and the collar has two tentaculated arms. ''Rhabdopleura'' is the best studied pterobranch in developmental biology. ''Rhabdopleura'' is the only extant graptolite. Taxonomy This small order is monotypic. It has only a single extant genus, containing four to six living species.

Graptolites
Graptolites are a group of colonial animals, members of the subclass Graptolithina within the class Pterobranchia. These filter-feeding organisms are known chiefly from fossils found from the Middle Cambrian (Miaolingian, Wuliuan) through the Lower Carboniferous ( Mississippian). A possible early graptolite, ''Chaunograptus'', is known from the Middle Cambrian. Recent analyses have favored the idea that the living pterobranch ''Rhabdopleura'' represents an extant graptolite which diverged from the rest of the group in the Cambrian. Fossil graptolites and ''Rhabdopleura'' share a colony structure of interconnected zooids housed in organic tubes (theca) which have a basic structure of stacked half-rings (fuselli). Most extinct graptolites belong to two major orders: the bush-like sessile Dendroidea and the planktonic, free-floating Graptoloidea. These orders most likely evolved from encrusting pterobranchs similar to ''Rhabdopleura''. Due to their widespread abundance, plantkonic l ...
