| Summary: | Individual photo-identification studies of southern right whales (Eubalaena australis) during their nursing season have been undertaken along the southern Brazilian coast from fixed-wing aircraft from 1987 to 1994, and 1997. Photo-identification data were also obtained from a small inflatable boat from 1995 to 1998 and from helicopter in 1998. Surveys had unequal area coverage and photographic effort over the years. The present catalogue includes 85 right whales identified based on natural marks. Although three adult females (mother/calf pairs) photographed off Laguna, Santa Catarina ( ~ 28o29´S, 48o45´W), Brazil, were matched with previously photographed individuals from Península Valdés, Argentina ( ~ 42o30´S, 63o30´W) (Best, 1993), there have been no reported inter-annual resighting within Brazilian waters. An adult female accompanied by a calf photographed in Santa Catarina in 1995 was resighted in 1998 with another calf within the same stretch of coast (27º52´-28º31´S). During the 1995 season the mother/calf pair was sighted on six occasions within a 20km range from September to October. In 1998 the mother and calf pair were sighted four times in an interval of 39 days from August to September, along 70km of coast. This represents the first resighting of a southern right whale along the Brazilian coast and indicates that at |
