Why is the cookie cutter shark called the cookie cutter?
Many cetaceans and large fish, including other sharks, suffer when cookiecutter sharks are around. This small, cigar-shaped shark is a parasite that bites chunks out of its prey. Using its unique thick, flexible lips to hold onto its victim by suction, it then twists itself around so that its razor-sharp lower teeth bite out a cookie-shaped piece of flesh. It is active at night, luring its victims with glowing green bioluminescent lights on its belly. It also preys on squid and crustaceans.
What if a shark cut you and off how do you treat it?
If a shark cut me off I would honk my horn until he looked and then maybe give him the middle finger. Unless he was a big white or a hammerhead in which case I would just honk. Sharks are terrible drivers and I am not even sure why we give them licenses in the first place.
Make sure
- there are no police around because they could pull you over for being a disturbance
- you keep paying attention to the road and other cars after it cuts you off
- if you practice defensive driving you will be safer!
- keep your cool! if a shark cuts you off and you are going to be late maybe next time you could remember to leave earlier!

The largest species of shark that is still existent is the Whale Shark. This species of shark can measure up to 40 feet long (that's 12.2 meters). They feed on plankton, sifting enormous amounts through their filter like gills.
The largest species of shark to have ever lived is thought to be the Megalodon. This species is now extinct. It is believed to have existed during the prehistoric era, and has not lived for millions of years. It is thought that this giant shark could measure up to 59 feet long (18 metres). Some cryptozoologists believe that this creature may still be alive today, living in very deep waters, but such claims have earned little credibility in the scientific world.

The largest species of shark is also the largest fish in the ocean, the whale shark. Despite reaching lengths greater than thirty feet (10 m), they feed only on small organisms such as krill, due to their tiny gullets. They are quite harmless to humans (and most larger species), and are popular tourist attractions in Mexico when they migrate during the summer months. It's possible even to swim with them.
The megaladon was the largest shark in the world, weighing 50 tons and being about 15 meters long. Its jaws are so massive it could probably swallow a bus. It became extinct supposedly, but many people and scientists believe they're still out there. A sort of spin off from the lockeness monster
