The Southern elephant seal is the largest seal on the planet. Males are much larger than females and have a long nasal proboscis that helps in mating fights and attracting mates.
The Southern elephant seal differs from other seals by the enormous size of males and the long proboscis. It is important for nature as a large predator that regulates the population of fish and squid in the southern seas.
