Who would win a fight between a sea lion and a seal? What happens if you add a walrus to this mix?

Leopard seals in the Antarctic are known to be aggressive hunters and have attacked people before. (file)

Seal vs. Sea Lion vs. Walrus: Key Differences

Which is more dangerous?

While all three species are wild animals and should be treated with caution, walruses are generally considered the most dangerous.

Walruses

• Size & Power: A male walrus can weigh up to 4,400 lbs (2,000 kg) and has enormous tusks that can cause severe injuries.
• Aggressive Defense: They are territorial and protective, especially mothers with calves. If threatened, they can attack boats and humans.
• Deadly in Water: With their powerful flippers and bulk, they can easily capsize small boats.

Sea lions

• More aggressive than seals but not as dangerous as walruses.
• Males (bulls) are territorial during mating season and can attack if provoked.
• Strong bite: They have sharp teeth and a powerful jaw.

Seals

• Generally timid and avoid humans.
• Exception: Leopard seals in the Antarctic are known to be aggressive hunters and have attacked people before.
• Sharp teeth but rarely attack unless provoked.

How can you stay safe when interacting with any of these animals?

• Keep your distance when observing them in the wild.
• Never feed or provoke them.
• Be cautious in water—even playful behavior can be dangerous.
• Respect their habitat to avoid aggressive encounters.

If we were talking about the most dangerous one, a walrus would win the crown due to its size, tusks, and aggression. As for the most aggressive, it would be a sea lion, especially territorial males. A seal is the least threatening out of the three unless it’s a leopard seal.
