Última Shallow-water Niphatidae (Haplosclerina, Haplosclerida, Demospongiae) from the São Sebastião Channel and its environs (tropical southwestern Atlantic), Naturalis Pinheiro, U.S.; Berlinck, R.G.S.; Hajdu, E.. Two niphatids are described here: Amphimedon viridis and Pachychalina alcaloidifera sp. nov. Amphimedon viridis is a common and conspicuous species in most of the tropical western Atlantic. Pachychalina alcaloidifera sp. nov. has this far been found only in the coasts of Rio de Janeiro and São Paulo states. Both species are described on the basis of series of specimens observed alive.

Biogenetically unrelated cyclic guanidine alkaloids and pyrroloquinoline alkaloids have been reported from sponges assigned to the genus <i>Batzella</i>. These sponges have been assigned to this genus because of their possession of a simple complement of thin strongyles in irregular plumoreticulate arrangement. Cyclic guanidine alkaloids were first reported from an alleged axinellid species from the Caribbean, <i>Ptilocaulis</i> aff. <i>P. spiculifer</i>, and subsequently from a second Carribean specimen identified as <i>Ptilocaulis spiculifer</i> and at the same time from a Red Sea poecilosclerid, <i>Hemimycale</i> sp. Closely related compounds were described from a Caribbean specimen identified... Tipo: Info:eu-repo/semantics/article Palavras-chave: Alkaloids; Chemotaxonomy; Batzella; Poecilosclerida.
