Annelid

The annelids (also called "ringed worms" or "segmented worms"), formally called Annelida (from Latin anellus "little ring"), are a large invertebrate phylum, with over 17,000 modern species including ragworms, earthworms and leeches. Various forms specialise in their respective ecologies; some in marine environments as distinct as tidal zones and hydrothermal vents, others in fresh water, and yet others in moist terrestrial environments.

Union science knows a large number of annelid life forms. Butr so far only one species that could be classed as an Annelifd has the potential of higher brain functions that could lead to sentience. (The large KIltri worm of Narl  Mongu a planet of the Nul )
