The occurrence of Sotalia guianesis and their group size and composition in Paraty Bay, Rio de Janeiro, are described for the period October 2000 - September 2001. During this period, 36 cruises and 6718min (45,19%) of direct observation were accomplished. Sightings were made in all seasons (in 94.5% of all cruises), during which time 54 groups (total of 1,754 individuals: mean=32.4 individuals/group) were observed. The size of each group varied from one to 100 specimens. The total number of individuals per unit effort and their group size varied seasonally. Groups with 31-40 individuals were the most often observed (25.9% of all groups). Significant differences between group size frequency and season, type of activity were seen. No signifi...
