Geonemertes pelaensis

Geonemertes pelaensis is a species of terrestrial Nemertea. Superficially, Geonemertes pelaensis resembles a land flatworm (family Geoplanidae) and lives in the same habitat, but it has an anterior exertile proboscis, whereas flatworms have a pharynx located in their ventral side at midlength of body. The number of eyes this nemertean can have varies between 4 and 8 ocelli.

It is commonly found on islands in the Indo-Pacific, and has been anthropogenically introduced to Caribbean islands and Florida. Geonemertes pelaensis is a known predator of gastropoda in the wild, and isopoda, and amphipoda in laboratory settings.
