A shark is a vital part of the Oceanic Ecosystem. It regulates the food chain. It eats smaller sea creatures, thinning down those populations. It is hunted down by other sea creatures, providing food. That is only part of a shark's job, but it is a vital one.

no there should not be a law on banning sharks......they were made for a purpose in this world
yes
Great white sharks don't eat people on purpose. They mistake you for a seal if your on a surf board or if your in a wet suit. Bull sharks on the other hand they don't care what you are, if they are hungry, they will eat you. Bull sharks have the highest testosterone level than any other shark.
Filter feeding Sharks, like the Basking Shark and the whale Shark eats plankton on purpose. Other Sharks might get some by accident.
To increase the surface area of the stomach
It depends on what kind of shark it is. The sharks mistake swimmers for seals and other pray. It doesn't happen on purpose.
Male sharks have two external reproductive organs called claspers, which serve the same reproductive purpose as a penis.
A little bit of both really. Sharks bite people on purpose because they accidentally mistake us as seals.
a sharks coloration has to do with their surroundings and they seem to blend in with the other water and it helps them capture their prey
Im pretty sure they do ,But not on purpose though. They(The plankton) are so small im sure its accidental.
Nurse Sharks, Lemon sharks and Hammerhead Sharks
