Leopard seals are one of the most challenging top predators to examine due to the severe temperature in Antarctica, the species' solitary lifestyle, and its fatal reputation.
An extraordinary finding has been made on the basis of scat and scars found on the bodies of leopard seals. Leopard seals from New Zealand have been discovered to be the first in the world to eat sharks, making them members of a very small and specialized group of marine predators that prey on the animal.
