📖 1. Overview
The Galapagos Sea Lion is an endemic species living only on the Galápagos Islands, where females, young, and one dominant male form groups of about 30 individuals. It is also an animal that attracts tourists.
🦴 2. Anatomy & Morphology
A male's fur looks black when wet and dark brown when dry, and fully grown males develop a light gray back. Females, young males, and pups are light brown to tan, while adult males have a thicker neck, shoulders, and chest and a prominent crest on the back of the head.
🔍 3. Ecology & Behavior
It hunts fish, squid, octopuses, and crustaceans in shallow water, smashing octopuses against the water's surface to make them easier to eat. The breeding season is long, lasting from May to January (months 5–1), and after an 11-month gestation a single pup (about 6 kg) is born and weaned at 11–12 months.
🇰🇷 4. Connection to Korea
