PROPOSAL FOR INCLUSION OF SPECIES ON THE APPENDICES OF THE CONVENTION ON THE CONSERVATION OF MIGRATORY SPECIES OF WILD ANIMALS A. PROPOSAL: Include the Atlantic humpback dolphin Sousa teuszii (Kükenthal 1892) on CMS Appendix I B. PROPONENT: Senegal

The Atlantic humpback dolphin is a small delphinid regionally endemic to the tropical and subtropical eastern Atlantic nearshore waters of West Africa (Culik, 2002; Jefferson et al.). Its status was recently and comprehensively reviewed as part of the CMS/UNEP Wafcet-2 project (Van Waerebeek et al., 2003, 2004). S. teuszii was described in 1892 from a carcass found in Cameroon. Second and third specimens were collected respectively in 1925 and 1943 in Senegal. Next it was sighted south of Conakry, Guinea, in 1953. Over the next half-century it was encountered in Dakhla Bay (Rio de Oro/Western Sahara), Banc d'Arguin (Mauritania), SinéSaloum delta (Senegal), Niumi National Park (The Gambia), Canal do Gêba-Bijagos (GuineaBissau), southern Guinea, Gabon Estuary and finally in southern Angola, but it has never been considered a common species (Beaubrun, 1990; Robineau and Vely, 1998; Van Waerebeek et al., 2003; Collins et al., 2004).
