The Steller sea lion is a large marine mammal found along the coasts of the North Pacific Ocean, particularly in areas like Alaska and California. They are known for their impressive size, with males weighing up to 1,000 pounds and measuring up to 10 feet long. Their thick fur ranges from light brown to yellowish, and they have a distinctive mane. Steller sea lions are social animals that often gather in large groups on rocky shores and beaches. They primarily feed on fish and squid, using their keen eyesight to hunt. These sea lions are also known for their vocalizations, which include barks and growls, especially during breeding season.
