Contribution to the census of cetacean in the Guadeloupe archipelago
In 325 surveys, 518 visuai observations and acoustic 202 have identified four families, 14 genera and 17 species, representing a cumulative total ofnearly 6000 cetaceans assessed within 15 miles of coastal water ofGuadeloupe. Dolphins (Delphinidae), constitute 33% ofthe 36 species currently known in...
