Cnidários da Baía do Espírito Santo e adjacências (Brasil). I - as anêmonas-do-mar (Anthozoa, Actiniaria)

A riqueza de espécies de actiniários foi estudada numa área (complexo portuário de Tubarão - Praia Mole, na costa sudeste brasilera) diretamente impactada por efluentes de uma usina de pelotização de minério de ferro. Até o momento foram identificadas treze espécies de anémonas na região; cinco outras continuam sendo estudas. Duas espécies têm sua distribuição ampliada ao longo da costa brasileira: Anthopleura varioarmata, ao norte e A. krebsi, ao sul. São discutidos ainda, de modo conciso, problemas relacionados com a coloração de algumas espécies.The species richness of actiniarians was studied in an area (Tubarão - Praia Mole Harbour at Vitória, Espírito Santo state, southeastern Brazil) directly impacted by wastes from an iron ore pelletizing plant. To date, thirteen species of sea anemones have been identified from the region. Five others are still being studied. Distributions of two species have been extended along the Brazilian coast, with the known range of Anthopleura varioarmata increased to the north and that of A. krebsi to the south. Questions concerning the colour of a few species are briefly discussed

Hydroids (Cnidaria, Hydrozoa) collected on the continental shelf of Brazil during the Geomar X Oceanographic Operation

Hydroids (Cnidaria, Hydrozoa) of the intertidal zone of Governador and Paquet\ue1 islands, Guanabara Bay, Rio de Janeiro, Brazil

During six consecutive months, sampling were made at three points located on Governador Island and three on Paquetá Island in Guanabara Bay, Rio de Janeiro, Brazil. Material was collected from dock pilings and rocks in the intertidal zone. In these samples, five species belonging to three families, Corynidae, Kirchenpaueriidae and Campanulariidae, were identified. The campanulariid species Obelia dichotoma Linnaeus, 1758, dominated at nearly all points sampled. The small number of species obtained in this survey is attributed to the intense pollution in the bay, which borders the second-largest industrial complex and the second-largest demographic center of Brazil
