Phoronida is a phylum of marine invertebrates, which have worldwide distribution and usually form huge benthic aggregations. The taxonomy of phoronids is still vague. In world fauna, there are 13 species of phoronids, but more than 40 larval “species”

Phoronids can be a major component of benthic and planktonic marine communities. Currently, the phoronid world fauna includes ten recognised species, known from adults; however, at least 32 larval forms have been described or documented. This study examined

Phoronids have worldwide distribution and are found in almost all seas of the World Ocean. Frequently phoronid larvae (actinotrochs) comprise a significant proportion of the total zooplankton biomass that makes their studies a very important source of
