Large Predators
Large predators have special adaptations to kill their prey. Polar bears, killer whales and great white sharks are some of the large predators found on earth.
The polar bear largely feeds on seals. The killer whales eat seals, sea lions, fish, etc. The great white sharks are the most dangerous ocean predator and feed on almost every organism.
Small Predators
Small predators do not cause mass destruction. E.g. sea stars feed largely on various types of shellfish. The ladybug is the smallest predator that feeds on aphids.
Other predators include lions, tigers, bears, wolves, leopards, dogs, snakes, crocodiles, etc.
