Abstract
In July 2000 the DIVA-1 Expedition collected deep-water benthos (5125-5449Â m) in the Angola Basin, South Atlantic Ocean. The tanaidacean material is composed of 434 individuals with a body length between 1.2 and 12Â mm. Sixty-eight species, belonging to 10 families were found. Tanaidomorpha with 63 species represent 96% of the material, Neotanaidomorpha with one species 3% and Apseudomorpha with 4 species 1%. The most diverse genus is Leptognathia (22 species). The material is dominated by Paranarthrura angolensis with 58 individuals. The Tanaidacea of the Angola Basin share only one species (Neotanais americanus) with other deep-sea areas of the Atlantic Ocean, 97% of the material is composed of new species. The different sampling gear results are discussed.
