The Leopard shark:
The leopard shark swims along the bottom of the ocean floor causing him to mostly eat different bottom feeders, such as shrimp, crab, and other bony fish such as anchovies, herring flat fish etc. I however am going to take a look at the crab the leopard shark consumes. The crab has its hard shell to defend itself from such predators, but with tooth rows numbering up to 55 teeth in the upper jaw and 45 in the bottom, the leopard shark is allowed to easily bypass the hard shell of the crab.This is where the leopard shark takes the energy given to him by the crab.
Humpback whale:
The humpback whale has developed different ways of hunting his prey. He eats krill. One way the humpback whale is able to consume his prey is by swimming into swarms of krill, sucking in tons of water and at the same time, tons of krill. Because he sucks so much water he has to expand his throat. As the water exits through the baleen plates the food gets stuck behind them. The krill are mostly defenseless to this tactic, and there best bet at survival is to swim away as fast as possible.
Marlin:
The marlin mostly hunts fish such as the black fin tuna. The marlin tends to mostly hunt during the day and alone, very rarely gathering in schools. The marlin tend to use there long famous jaw, or bill, as a weapon to stun or wound their prey. Another major advantage the marlin has, is its incredible speed. They can travel as fast as a hundred miles an hour, and can turn on a dime. This allows them to catch their small prey.
