摘要

Sea stars from the Brazilian continental margin, Southwest Atlantic, have been sampled through two major Brazilian deep-sea programmes in collaboration with the Research and Development Center of the Brazilian Energy Company PETROBRAS: 'Campos Basin Deep Sea Environmental Project', and 'Campos Basin Deep-Sea Coral Assessment Project'. Amongst these sea stars the Order Brisingida, Family Brisingidae and two of its species have been recognised for the first time for Brazilian waters: Brinsiga sp.; and Novodinia antillensis (A.H. Clark 1934). The order Brisingida (Fisher 1928) includes deep-sea asteroids mainly recognized by having a small, circular disc, bearing more than five long, slender arms bearing spines and pedicellaria. The genus Brisinga comprises four Atlantic species (B. costata, B. cricophora, B. endecacnemos, B. hirsuta) mostly characterized by the spines around the mouth, furrow and subambulacral regions. A single damaged specimen of Brisinga sp.1 was sampled with an OTSB, and this is either just a new occurrence for the Atlantic or a new species, but further detailed investigation is required to evaluate the status of this species. A total of 94 individuals of N antillensis were observed through ROV video transects. Most of them were found perching high on hard biological substrates as Scleractinia (Caryophylliidae) and Hexactinellida (Farreidae) possibly feeding on suspended material. Even though the Brazilan SE offshore region is considered oligotrophic, the abundant presence of brisingid sea stars in association with coral banks suggest an energy rich deep-sea environment at Campos Basin.

Costata，B.Cricophora，B. EndecConemos，B.Hirsuta）主要是口腔，沟槽和脱泥地区周围的刺。用OTSB对Briscea SP.1的单一受损标本进行采样，这只是大西洋或新物种的新发生，但需要进一步详细的调查来评估该物种的状况。通过ROV视频横断面观察到总共94个Antillensis。其中大多数被发现栖息在硬菌菌（Caryophylliidae）和六乳糖蛋白酶（Farreidae）上的硬质生物底物上栖息高，可能会在悬浮材料上喂养。尽管巴西伊斯兰近海地区被认为是寡营养学，但是与珊瑚银行相关的Bristid海星的大量存在表明坎普斯盆地的能量丰富的深海环境。
