Leopard seals in New Zealand have a dangerous appetite. Although the animals were known to eat penguins and other seals, researchers only recently discovered that sharks were on the menu as well, which was really surprising. They made this discovery while analyzing fecal samples collected from more than 100 leopard seals.
Leopard seals appear to have joined a growing list of animals (orcas, giant octopus) that dine on what we humans fear as the most dangerous animal in the ocean. Maybe the next Jaws sequel should feature a heroic leopard seal?
