What animal kills a shark?
Orcas are the real apex predators of the ocean. Killer whales may be the only animals on our list that actually prey on great white sharks. Otherwise known as orcas, these intelligent mammals belong to the dolphin family and are probably the top predators in the entire ocean. Indeed, the great white shark (Carcharodon carcharias) leads all other sharks in attacks on people and boats, as well as fatalities. Currently, the great white shark has been connected with a total of 354 total unprovoked shark attacks, including 57 fatalities [source: ISAF].Attacks are extremely rare and people are rarely consumed by sharks. A shark is capable of eating someone if they wanted to but it often doesn’t, which suggests we’re not considered prey and certainly not targeted, so that should allay a lot of fears.
Which jaw does a shark bite with first?
Sharks have unique jaws as unlike most animals, both their upper and lower jaws move. When a shark bites something, they bite first with the lower jaw and then with their upper jaw. Shark teeth vary based on species and diet. By replacing their teeth regularly, they ensure their teeth remain useable so they can eat. In this way, some species of shark can go through 30,000 teeth in their lifetime. In species such as the cookiecutter shark and the kitefin shark, they’ll lose the entire lower plate of teeth in one go.
