Description 
Summary

This population has been followed since 1981. Individuals are recognised by specific features (shape and marks of dorsal fin) by means of photographs. Movement of groups and individuals are monitored by means of theodolite. Individuals are followed by boat and a catalogue of their natural sounds is being compiled. Several individuals have been identified for several years. The population is basically sedentary and the individuals form subgroups of variable composition, maintaining only temporary association, except for mother and infant.
