The Elephant Seal is a large marine mammal found in the sub-Antarctic and Antarctic regions. Belonging to the family Phocidae, they are divided into two species: Northern and Southern Elephant Seals. These creatures are known for their massive size, with males weighing up to 8,800 pounds and measuring up to 20 feet in length. They have a distinctive proboscis, which resembles an elephant's trunk, used for vocalization and attracting mates. Elephant Seals are expert divers, reaching depths of over 5,000 feet and staying submerged for up to two hours. They primarily feed on fish and squid, and face threats from climate change and human activities.
