متن کاملTwo new species of Distaplia (Tunicata: Ascidiacea) from the SW Atlantic, Argentina.
The ascidian fauna from the Southwestern Atlantic (Argentine Sea) have scarcely been studied and have rarely been sampled. The existing scanty ascidian records are from specimens collected by dredging many decades ago. During samplings in the San Matias Gulf (Río Negro, Patagonia), two new Distaplia species were found. Distaplia naufragii sp. nov. was collected in the subtidal zone attached to ...
متن کاملHuman-mediated global dispersion of Styela plicata (Tunicata, Ascidiacea)

Although S. plicata has been historically classified as a cosmopolitan species, in the past few deca...
متن کاملNew species of Didemnidae (Tunicata: Ascidiacea) from the tropical coast of Brazil.
The family Didemnidae includes 20% of all known ascidians with six genera in the Atlantic. Here, we describe five new species in the Didemnidae from central coastal Brazil. Four species are in the genus Didemnum and were found in Bahia (D. aurantium, D. flammacolor, D. lambertae, D. longigaster), while one Diplosoma (D. citrinum) was found both in Bahia and Espírito Santo.
متن کاملCytotoxicity of the crude extracts of Marine ascidians (Tunicata: Ascidiacea) from Tuticorin, Southeast coast of India
Marine organisms such as ascidians, sponges and soft corals, containing symbiotic microorganisms are a rich source of bioactive compounds. This study examined the cytotoxic potential of two ascidians found in the coastal waters of Tuticorin. The ascidians samples Didemnum psammatode and Phallusia arabica were extracted in methanol and ethanol. The crude extracts were tested for cytotoxicity usi...
