The phylum Nemertea is in the kingdom Animalia, and the super phylum Lophotrochozoa. It is home to approximately 1150 different species. These species differ in trophic association along with the environments they are found in. Species of Nemertea have been found to be scavengers, parasites, and herbivores. But the common Nemertean worm is 10-15 cm long, circular, found in a marine habitat and is a carnivorous predator. Fresh water (12 sp.), pelagic, deep water, and terrestrial (approx 15 species; found in tropical areas where it is damp and humid) also exist.
