The Southern Elephant Seal
The Southern Elephant Seal, also known as Mirounga leonina, is the largest seal species in the world. These marine mammals can reach lengths of up to 20 feet and weigh around 8,800 pounds. One of their most distinguishing features is their large, protruding noses, called "trunks," which males develop upon reaching sexual maturity. Southern Elephant Seals have a dark gray to brownish-black coloration with a lighter shade on their undersides. They are excellent divers and can hold their breath for up to two hours. These seals are found primarily in the sub-Antarctic and Antarctic regions.
