📖 1. Overview
The Northern Elephant Seal is a seal living in the eastern North Pacific whose adolescent males develop an elongated nose resembling an elephant's trunk. It spends most of 1 year at sea.
🦴 2. Anatomy & Morphology
Around age 7, males develop a large, inflatable proboscis that hangs about 8 inches (20 cm) below the lower lip. A thick neck covered in calloused skin acts as a shield during fights, whereas females have a smaller nose and smooth neck.
🔍 3. Ecology & Behavior
It eats squid, fish, rays, and sharks, diving for over 20 minutes at a time to depths of around 500–600 m. During the breeding season, dominant males control harems of females while lower-ranking males wait on the margins for a chance.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
