摘要

是巴西北部和东北部海岸和海洋岛屿的热带浅水中的主要章鱼。这种物种在大陆上的丰度、分布、栖息地和饮食与在海洋岛屿上的相同吗?在巴西北部里约热内卢Grande do north海岸的两个岛章鱼发生区域对这些因素进行了评估，以寻求这些答案。物种集中的三种主要栖息地类型为:深礁(Risca礁)(> -15 m)，平生高原(Restingas) (5-15 m)和浅沉积礁(Pirangi礁)(< 5 m)。证实了聚集的空间分布，以及小个体占据浅层区域的水深隔离。关于饮食,

Octopus insularis (Cephalopoda: Octopodidae) on the tropical coast of Brazil: where it lives and what it eats

is the dominant octopus in the shallow tropical waters of the coast and oceanic islands in the North and Northeast of Brazil. Is the abundance, distribution, habitat and diet of this species on the continent the same as in oceanic islands? These factors were evaluated in seeking these answers at two areas of occurrence of Octopus insularis on the coast of Rio Grande do Norte, Brazil. Three main types of habitats were described where the species is concentrated, being: Deep Reefs (Reefs of Risca) (> 15 m), Flat Biogenic Plateaus (Restingas) (5-15 m) and Shallow Sedimentary Reefs (Pirangi reefs) (< 5 m). An aggregate spatial distribution was verified, along with bathymetric segregation in which small individuals occupied shallow areas. Regarding diet,

期刊介绍： The Brazilian Journal of Oceanography covers the entire spectrum of disciplines within the science of oceanography, publishing articles dealing with the biological oceanography, physical oceanography, marine chemistry, sedimentology and geology, from coastal and estuarine waters out to the open sea. Emphasis is placed on inter-disciplinary process-oriented contributions. BJO also publishes issues dedicated to results of scientific meetings and of large inter-disciplinary studies or topical issues on specific subjects. The audience is composed by physical, chemical and biological oceanographers, marine sedimentologists, geologists and geochemists, marine biologists and ecologists. Papers sent to BJO must present results from original research and be written in english.
