Abstract: ABSTRACT. 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.KEYWORDS. Cnidarian, hydrozoan, siphonophore, pleuston, systematics.RESUMO. Redescrição taxo… Show more

“…Its main features are the presence of a gas bladder, or pneumatophore, and several tentacles comprising typical cell populations with different functions (dactylozooid, gastrozooid, and gonozooid). Morphologically, the Portuguese man-of-war exhibits vibrant coloring that may vary from green to lilac 4 .…”

“…The medusae of hydroids are usually distinguished clearly in the biological literature. However, for siphonophores, the interpretation of medusae and their related polymorphs present difficult problems Bardi and Marques, 2007); in the nineteenth century, these were further confounded with problems of coelenterate (now cnidarian plus ctenophore) classification (Winsor, 1972(Winsor, , 1976. 9 Leuckart asserted that polymorphic individuals in colonies of hydroids, siphonophores, and other groups had often been ''misunderstood'' as ''mere organs'' (Leuckart, 1851a, p. 12).…”

“…This species is a colony of numerous polyps (Totton and Mackie, 1960;Bardi and Marques, 2007). One of the polyps develops into a gas-filled float that looks like a sail (pneumatophore) and others develop into digesting polyps (gastrozooids), reproductive polyps (gonozooids) and long defending and hunting tentacles (dactylozooids).…”
