1. The Clymene dolphin Stenella clymene is found in tropical and warm temperate waters of both the North and South Atlantic Oceans. Confusion surrounding the identifying characteristics of this species has contributed to a general lack of knowledge of this species. 2. We collected and verified a total of 195 records (109 sightings, 67 strandings, and 19 captures) of Clymene dolphins. Twenty‐five per cent (n = 49) of these records were previously unpublished. Rejected records are discussed in order to clarify the literature. 3. The northernmost locations for the Clymene dolphin are 39°17′N, 74°35′W (NJ, USA) and 19°1.9′N, 16°13.5′W (113 km north of Nouakchott, Mauritania). The southernmost locations are 29°58′S, 50°07′W (Tramandaí, Rio Grande do Sul, Brazil) and 3°40′S, 18°5′W (off Ascension Island). 4. Clymene dolphins were found in waters with bottom depths ranging from 44 to 4500 m (mean = 1870 m; SE = 110 m; median = 1675 m; n = 94). A single sighting reported at a location with a bottom depth of 44 m is considered to be atypical, as this species has an otherwise exclusively oceanic distribution. 5. Group sizes ranged from at least one individual in a mixed‐species school of spinner dolphins Stenella longirostris to a group of an estimated 1000 animals (mean = 76.1; SE = 11; median = 47; n = 105). Stranding group size ranged from 1 to 46 individuals (n = 67), with single individuals being most common (n = 60). There is information available for seven mass strandings, all of which occurred in the south‐eastern USA.

“…Distribution and natural history. A sighting in deep oceanic water at 02° 10' N, 02° 30' W, some 160 nm south off Axim port, equivocally assigned to S. longirostris (Leatherwood et al, 1976), was recognized as S. clymene (Perrin et al, 1981;Robineau et al, 1994). From temporal distribution of captures, Clymene dolphins appear to be present year-round in Ghanaian waters.…”

The cetaceans of Ghana and the Gulf of Guinea have, until recently, remained unstudied. Periodical monitoring of artisanal fisheries for bycatches in seven Ghanaian artisanal fishing ports and landing sites over 1996-2004 has provided photographic and specimen evidence to validate occurrence of 18 species (17 odontocetes, 1 mysticete) in a tropical, predominantly pelagic cetacean fauna. At least nine species and subspecies had not previously been documented for Ghana (with asterisk), and four species are authenticated for the first time in the Gulf of Guinea (double asterisk), i.e.

A review indicates that nineteen species of dolphins and porpoises (cetacean families Delphinidae and Phocoenidae) occur in West African waters (from the Strait of Gibraltar to the Congo River). In addition, two other cold temperate species reach their southern limit at the northern border of the area. For each species, distribution records in West African waters are reviewed. A key to dolphins and porpoises of West Africa, based on external appearance, is presented to aid in identification.Resume. -Une recherche bibliographique a permis de denombrer dix-neuf especes de dauphins et marsouins (Cetaces : Delphinidae et Phocoenidae) dans les eaux de l'Afrique de lOuest (dcpuis le Detroit de Gibraltar jusqu'au fleuve Congo). De plus, deux especes vivant dans des eaux froides et temperees atteignent leur limite sud de repartition ä la frontiere nord de cette zone. La distribution de chaque espece en Afrique de 1'Ouest est passee en revue. Une cle d'identification des dauphins et marsouins de l'Afrique de 1'Ouest, basee sur la morphologic externe, est proposee en vue de faciliter la determination.
