A collection of 185 cephalopods from near the southern end of Fuerteventura(Canary Islands) consists of 18 species and 13 unidentified larval specimens. The collection is particularly interesting because the use of modern closing nets and depth monitoring gear has thrown new light on the depth distribution of some of the cephalopod species concerned. Diurnal migration is described for several oceanic cephalopods for the first time.
