Scientists of the Smithsonian Institute of tropical research in the US discovered several new types of larvae phoronid whose adult forms are unknown. About it reported in a press release on Phys.org.
Zoologists have collected samples of plankton from Panama Bay (Pacific coast) and the Caribbean (archipelago of Bocas del Toro). They identified 50 larvae phoronid — invertebrate worm-like body, tentacles and chitinous tube, one end of which is immersed in sludge or sand. DNA analysis helped to identify the three species from Panama Bay and four from the Caribbean.
However, certain stretches of DNA, each of the detected species was unique among the genomes stored in the GenBank database, which presents the collection of DNA of more than 300 thousand organisms. This indicates that scientists have found a new species, however, the search for adult forms can take years. According to the researchers, there is a possibility that they will never be found due to the fact that the way of life of these invertebrates very little is known.
Phoronid larvae are free-swimming, while their adult forms are attached to the sea ground. This explains why it is easier to detect larval form, and not Mature individuals.
