Pacific sleeper sharks, which are also known scavengers, can glide through the water with little body movement and little hydrodynamic noise making them successful predators. They feed by suction and cutting of their prey. They have large mouths that can inhale prey and their teeth cut up any pieces that are too large to swallow. They show a characteristic rolling motion of the head when feeding. Only in Alaska has the shark's diet been studied - most sharks' stomachs contain remains of giant Pacific octopus. They are also known to feed on bottom-dwelling teleost fishes as well as soles, flounders, Alaska pollock, rockfishes, shrimps, hermit crabs, and even marine snails.

If a bull shark and hammerhead shark were to fight, the bull shark would win. Bull sharks are the most dangerous sharks in the world! Along with this, bull sharks have special adaptations, and they hunt in shallow waters. Although hammerhead sharks have great vision, the shape of their heads, and the placement of their eyes cause them to have a huge blind spot right in the middle of their head. This makes it easier for other sharks to win a fight against the hammerhead.

This is the shark’s Real Bite.

Sharks have been in existence for more than 300 million years. Their evolution occurred over 150 million years earlier than that of the dinosaurs. Most of the existing fossil data of early sharks was collected from fossilized teeth together with several skin impressions. primitive sharks (Cladodonts) , had teeth which were double-pointed, up to 2metres in length, ate fish as well as crustaceans, and existed approximately 360 million years ago.

This organism causes the sharks to go blind. Luckily Greenland sharks are mainly scaevngers and heavily rely on their heighted sense of smell.
