Baby elephant seals and female elephant seals are pleasant looking. But males begin developing a large nose when they reach sexual maturity, somewhere around three to five years, reports The Marine Mammal Center. The huge proboscis is fully developed by seven to nine, giving the seal the look of its namesake elephant with a massive, floppy trunk.
Elephant seals are capable of making loud, roaring snorts, a handy tool in defending territory. They are also deceptively fast. Some elephant seals have been clocked wiggling over sand dunes at a speed faster than the average human can run!
