The Caribbean coast of Martinique has a great wealth of marine mammals, with almost twenty species observed, including the short-finned pilot whale Globicephala macrorhynchus. Little is known about this specie in Martinique. Boat surveys between "le rocher du Diamant" and "l'îlet la Perle" allow gathering data and pictures. Statistical analysis, SIG and photo identification provide first information on the pilot-whale population. Results indicate there is a rather small but healthy population of G. macrorhynchus in Martinique. It is composed of both resident and migrant groups and no seasonality was observed. Correlation between the percentage of teenagers and the number of boats might imply an effect of whale-watching on individuals.
