The cetacean fauna inhabiting the poorly-studied waters of the eastern tropical Atlantic (ETA), along the west coast of Africa, is still being described. Information on the cetacean species occurring in specific ETA range states is important for understanding their geographical distribution ranges and for implementing conservation and management measures. Here we provide photographically-verified records for the occurrence of pygmy killer whale (Feresa attenuata) off Côte d'Ivoire and of Fraser's dolphin (Lagenodelphis hosei) off Gabon. These records represent new range state records for both species, and are also the first verified at-sea sightings in the ETA and the Gulf of Guinea respectively.

A dead dolphin found on Bonaire in August 2011 is identified as adult Fraser's dolphin Lagenodelphis hosei, a new species for the Dutch Caribbean. A first closer examination showed a collapsed lung, stomach parasite infection and abundant mouth ulceration as indications of its health status. The animal was relatively fresh and did not die very long before it was found. Like more often with stranded deep diving cetacean species within the area, remnants of crustacean were found in its beak indicating recent foraging.
