Phoronis is one of the two genera of the horseshoe worm family (Phoronidae), in the phylum Phoronida. The body has two sections, each with its own coelom. There is a specialist feeding structure, the lophophore, which is an extension of the wall of the coelom and is surrounded by tentacles. The gut is U-shaped. The diagnostic feature that distinguishes this genus is the lack of epidermal invagination at the base of the lophophore. These worms are filter feeders.[1] They live on hard substrates or soft sediments in marine environments throughout the world.[2] They have different modes of reproduction which help with their success.
The scientific name of the larval form is Actinotrocha.
