When researching the diversity of benthic marine animals, pipes are often retrieved objects. They are often empty, which makes it difficult to identify their "owners". Usually such tubes are described as tubes of annelids, which gives rise in hydrobiology to an erroneous opinion about the high density of their settlements in a certain water area. In fact, these tubes often belong to the phoronids, and there are now several criteria by which the tubes of annelids can be easily distinguished from those of the phoronids.
MSU biologists have learned to distinguish between fossil tubes of phoronids and annelids
