Too many! Save the great whites!
No
Great white sharks have about 46 teeth for each five rows
lamellae is a part of him/her that senses electric impulses
they have been known to eat each other,yes they will eat each other youtube has a video about it.
Typically, sharks and dolphins avoid each other. On occasion however, sharks such as the great white will hunt baby dolphins. Dolphins are tough creatures and sharks have learned to ignore them, for the most part.
There are so many differnt types of sharks! Each one is individual, and has it's own charichterists. You can find many amazing lists from trushed-websights of types of shark speices! As of when I wrote this there are 440 classified shark species!
sometimes THEY DO! sometimes THEY DONT!
No. They are solitary creatures that have very little social interaction with each other outside of mating.
the great white shark, (the sharks kill each other off in the sack for food!)
Adult Great Whites are apex predators. Apart from the Orca (Killer Whale), there are no known predators that may attack or kill a Great White. In regions where both the Orca and the Great whites inhabit and compete for food, Orcas may attack and kill these sharks. Since Orca's are much larger than them, they can attack and even kill great whites.
If food is scarce, then the answer is yes. Some Great Whites will fight each other for food, usually ending with one shark eating the other. Sometimes when two Great Whites have mated, the female will eat the male for extra energy to lay the eggs. Sometimes the pups will eat each other! Just be aware that it is rare for domesticated sharks to eat each other. :). If someone says this is false, they are wrong. :D
They have been known to eat each other, but this is not terribly common. By and large, the two species avoid each other or only consume the other if it is dead. The primary reason for this is that the "food reward" in each case is offset by the possibility of being seriously injured by the target. YouTube has a documented Orca vs Great White.
