Physical Characteristics
Elephant Seal Size and Weight
One of the most remarkable aspects of elephant seals is their impressive size. Elephant seals are renowned for their impressive size and weight. Adult males, known as bulls, can reach lengths of up to 20 feet (6 meters) and weigh an astounding 8,800 pounds (4,000 kilograms). They are significantly larger than their female counterparts, known as cows, who typically measure around 10 to 12 feet (3 to 3.7 meters) in length and weigh approximately 1,500 to 2,000 pounds (700 to 900 kilograms).
Elephant Seal Proboscis
One of the most distinctive features of male elephant seals is their elongated proboscis. This inflatable appendage, resembling an elephant’s trunk, plays a crucial role during territorial battles and courtship displays. When inflated, the proboscis amplifies the bull’s vocalizations, making them resonate across the beach and effectively intimidating rival males.
Elephant Seal Molting
Elephant seals undergo an annual molt, shedding their old fur and growing a new one. During this process, they spend several weeks on land, refraining from eating and focusing on regenerating their fur. The molt typically occurs after the breeding season, allowing the seals to replenish their energy and prepare for the challenges of the following year.
