Antarctic Peninsula: Leopard Seals
Leopard seal are amazing. I have never seen or imagined any animals like this. Second largest seal species after elephant seal, these are fierce predators, hunting other seals and penguins (we saw one thrashing a penguin like a stuffed toy). Their teeth are specialized for both large prey and krill. Only killer whales (orcas) can attack them and even that is rare. Their heads look like those of giant lizards, and they always have a characteristic smile. And a beautiful spotted fur coat!
