Annelid
The annelids (Annelida , from Latin ', "little ring"), also known as the segmented worms, are a large phylum, with over 22,000 extant species including ragworms, earthworms, and leeches. The species exist in and have adapted to various ecologies – some in marine environments as distinct as tidal zones and hydrothermal vents, others in fresh water, and yet others in moist terrestrial environments. The Annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Most textbooks still use the traditional division into polychaetes (almost all marine), oligochaetes (which include earthworms) and leech-like species. Cladistic research since 1997 has radically changed this scheme, viewing leeches as a sub-group of oligochaetes and oligochaetes as a sub-group of polychaetes. In addition, the Pogonophora, Echiura and Sipuncula, previously regarded as separate phyla, are now regarded as sub-groups of polycha ...

Erpobdellidae
Erpobdellidae is a family of leeches. It is one of the four families belonging to the suborder Erpobdelliformes of the proboscisless leeches order, Arhynchobdellida. Their members have abandoned the blood feeding habits of their ancestors and are instead predators of aquatic invertebrates. The family previously contained seven genera, but Siddall (2002) synonymized five genera (''Croatobranchus'', ''Dina'', ''Mooreobdella'', ''Trocheta'' and ''Nephelopsis'') into the genus '' Erpobdella'' based on morphogenetic analysis, with the remaining genus ''Motobdella'' possibly a sister group and thus retained. This decision was not accepted by scientific community. The family currently contains 3 genera ''Erpobdella'', ''Dina'' and ''Motobdella''. The genus '' Mimobdella'' was also sometimes included within Erpobdellidae or Gastrostomobdellidae Gastrostomobdellidae is a family of annelids belonging to the order Arhynchobdellida.
