Porpitidae

Abstract

In this section, we present one zoological family group at a time, as an example of animal variety. The family is a taxonomic unit containing a set of species having certain characteristics in common, the result of evolution, which testify to the origin from a single progenitor. This "portrait" is dedicated to Porpitidae, a family of Cnidarians Hydrozoans which contains only two genera: Porpita and Velella, both present in the Mediterranean.
