SOUZA, Christiane Sampaio de; CONCEICAO, Laura Rodrigues da  e  MAFALDA JUNIOR, Paulo de Oliveira. Hyperiid amphipods around the seamounts and islands off northeastern Brazil. Braz. j. oceanogr. [online]. 2016, vol.64, n.4, pp.339-352. ISSN 1982-436X.  http://dx.doi.org/10.1590/s1679-87592016123306404.

Data collected on large-scale surveys around the seamounts and islands off northeastern Brazil provide information on the hyperiid amphipod populations. Thirty-six species were identified. Most of the species belong to the Infraorder Physocephalata, representing 21 genera and 13 families. Thirteen species (Vibilia australis, L. latissimus, L. macrophthalmus, L. schizogeneios, Phronima atlantica, Phrosina semilunata, Primno brevidens, Eupronoe minuta, Oxycephalus clause, Rhabdosoma whitei, Amphithyrus bispinosus, Leptocotis tenuirostris and Tetrathyrus forcipatus) have not previously been recorded in this region. The spatial distribution of the hyperiid amphipods was very patchy. Each area of these amounts and islands off northeastern Brazil has different oceanographic features and can be characterised by a clearly defined group of most abundant species.
