There are only 3 types of sharks that are known to attack humans.
1) Bull Shark
2) Tiger Shark
3) Great White Shark
Sharks are highly intelligent,the brain-mass to body-mass ratio is closely
related to those of mammals and higher vertebrate species. The next
time you see a shark, basically think of them as a type of fish with a
cartilaginous skeleton with a streamline body and a lifespan of 100 years.
The largest of these sharks is the Whale Shark, this is a plankton eater
at 40 ft in length can weigh up to 13.6 tonnes (15 short tons).
This gentle giant can only be found in tropical and warm waters with
a lifespan of 70 years. Divers and snorkelers can swim with this giant fish
without any risk apart from unintentionally being struck
by the shark's large tail fin.
Cheers,
Simon
