Study reveals a diverse cephalopod fauna in the canary current large marine ecosystem

January 25, 2021

An extensive review of cephalopod fauna from the Northwest African Atlantic coast was performed by researchers from the University of Vigo (Spain) and the Spanish Institute of Oceanography (
The surveys were conducted by the IEO and the

After several years devoted to taxonomic study and the exhaustive review of the existing literature, an updated checklist of 138 cephalopods species was generated for the whole CCLME area. Besides, the known geographical distributions of several species have been expanded, as some deep-sea octopuses (such as Muusoctopus januarii, Bathypolypus valdiviae or Cirrothauma murrayi) and many oceanic squids (such as Abralia siedleckyi, Magnoteuthis magna or Chtenopteryx sicula), some recorded for the first time in the area.

The CCLME hosts one of the four major marine upwelling systems and is the third concerning primary productivity worldwide, supporting the largest fisheries of the Atlantic African coast, with an annual production of approximately 2-3 million tonnes. Among the main target commercial species are included some cephalopod groups as squids, cuttlefishes and octopuses.

Although most of the cephalopod species with commercial value in the region have been well-studied, many aspects of the systematic, distribution, biogeography and ecology of other cephalopods are practically unknown.

The EcoAfrik collections represent an exceptional source of information that will provide a global view on the biodiversity, composition and distribution of cephalopods from Northwest Africa.
