Deep sea benthic octopuses from Mauritanian waters: bring to light the Muusoctopus and Bathypolypus species
MetadataShow full item record
Mauritanian deep sea benthic octopods community is currently poorly known. This work shows the results obtained in the study of deep sea benthic octopods collected in four multidisciplinary Spanish-Mauritanian surveys (Maurit) conducted from 2007 to 2010 in Mauritania deep-shelf and slope. Samplings were taken using a bottom commercial trawl. Deep-sea benthic octopods community is composed by several poorly known species. Species as Amplioctopus burryi, Pteroctopus tetracirrhus, Scaeurgus unicirrhus, Bathypolypus ergasticus and B. sponsalis have been previously cited in these waters. Recently, six new benthic incirrated octopod species were recorded for the first time in Mauritanian waters: Muusoctopus fuscus, M. juanarii, B. arcticus, B. biardii, B. valdiviae and Graneledone verrucosa. These species seems to be a common element of benthic octopod fauna on the Mauritanian continental slope. It is possible that several of these species have already been caught in the region but may have ...
