摘要: Records of vagrant marine organisms provide important information on oceanographic anomalies and the changing environment. We report an immature Weddell seal, Leptonychotes weddellii, sighted at Calheta Beach in Trindade Island (20°31′S 29°19′W), Brazil, July 9, 2015. A number injuries were noted, including blisters dorsal surface body a small cut right-hand side distal portion mandible. Based its size state fusion cranial sutures, we suggest that it was born 2014 austral spring possibly 8–10 months old. comes from South Shetland Islands, Antarctic Peninsula. This is closest breeding location this species. sighting northernmost L. being least ~ 5140 km Peninsula (63°12′S 55°04′W) ~ 2840 km north second species Uruguay.
