Slightly smaller than their Californian relatives, Galápagos sea Lions range from 150 to 250 cm in length and weigh between 50 to 400 kg, with the males averaging larger than females. Adult males also tend to have a thicker, more robust neck, chest, and shoulders in comparison to their slender abdomen. Females have a longer, more slender neck and thick torso. Once sexually mature, a male’s sagittal crest enlarges, forming a small, characteristic bump-like projection on their forehead. Galápagos sea lions, compared to California sea lions, have a slightly smaller sagittal crest and a shorter muzzle. Adult females and juveniles lack this physical characteristic altogether with a nearly flat head and little or no forehead.
All over the Galapagos Islands. You can find them both in the water and in the sand beaches and rocky shores. Beware of getting in between males fights while wading in the water. Females and youngsters come to play and can fake biting your feet (sometimes is not so fake!)
