Redescrição taxonômica da caravela-do-mar, Physalia physalis (Cnidaria, Hydrozoa, Siphonophorae, Cystonectae) do litoral do Brasil

Abstracts

Although Physalia physalis (Linnaeus, 1758) is widely known from the Brazilian waters, specimens from this coast were never properly described. We describe Brazilian specimens of P. physalis including information on morphology, cnidome, SEM, and histological studies. Taxonomical issues concerning the development of the colonies and eventual synonymy with Physalia utriculus (La Martinière, 1787) are also added.
