Pinnipeds, semi-aquatic mammals of the order Carnivora, transitioned to the marine environment approximately 25 Mya. This transition was associated with many unique evolutionary pressures, including those affecting the brain. Here we investigate how a semi-aquatic lifestyle may have altered brain morphology in extant pinnipeds using magnetic resonance imaging (MRI) and gross anatomical observations on three spotted seals (Phoca largha, a Phocid) and three Steller sea lions (Eumetopias jubatus, an Otariid).Based on available data, we compared our observations on the semi-aquatic pinnipeds, to b
