South American Sea Lion
Otaria flavescensAlso known as Southern Sea Lion, Patagonian Sea Lion, Lobo Marino
South American sea lions are highly social marine mammals easily recognized by the dramatic physical differences between the sexes. Massive adult males develop a thick, lion-like mane of coarse fur around their swollen necks and can weigh over twice as much as females. During the breeding season, rocky beaches echo with the deep, guttural roars of territorial bulls defending their harems against younger rivals.

LC
Can deliver a powerful bite if cornered or approached too closely; maintain a distance of at least 50 meters.
Adult males can weigh up to 350 kilograms and are highly territorial, capable of charging quickly on land to deliver a severe bite.
Never block their path to the water, and slowly back away if they sit up, vocalize, or stare directly at you.- Keep your distance: Maintain at least 50 meters of space, especially during the breeding season when bulls are highly aggressive.
- Watch for warnings: Back away immediately if a sea lion vocalizes loudly, charges, or holds its ground.
- Keep dogs leashed: Pets can provoke defensive attacks and transmit diseases to marine wildlife.
