| A male specimen of Mirounga leonina Linnaeus, 1758 age estimated betvveen 7-8 years old, collected at Santa Vitória do Palmar, Rio Grande do Sul State, soutiiernmost Brazil (32º44'S and 53º22'W) is presented. Ali the skeleton was recovered except the rostral region. It shows an advanced osteomyelitis in the lefl dentary, extending from the synfisis until the middle portion of the body; as well as Scheuermann disease at lumbar vertebrae. Such diseases could explain its presence at that locality, where rt was shot. The bullct was recovered from the rostrum, and might be responsible for death. This is the first vhlually complete skeleton of M. leonina recovered from Brazilian coast. |

| The South American sea lion, Otaria flavescens (Shaw, 1800) population is steadily expanding along the Patagonian coast of Argentina in the last decades. However, little is known about the feeding ecology of the species in the area. The aim of this study was to analyze the food habits of O. flavescens from 91 scats collected at Río Negro province, during the winter and spring of 2005. Fish occurred in 96% of scats containing prey remains, followed by cephalopods (26%). Raneya brasiliensis (Kaup, 1856) was the most frequent and abundant species occurring in 58.6% of samples and constituting almost 50% of fish predated. Second in importance were Porichthys porosissimus (Cuvier, 1829) and Cynoscion guatucupa (Cuvier, 1830) in terms of occurrence (%FO 20.7)... |
