*Sharks Field Trip
 

 

Did you know that about 80% of the shark species have never attacked humans? Sharks are found in all the oceans of the world, but there are only four species that are considered dangerous: the great white shark (known to most of us courtesy of the movie "Jaws"), tiger shark, bull shark and oceanic whitetip shark. Humans are not the preferred food of sharks despite public hysteria and opinion to the contrary. Research suggests it to be a case of mistaken identity. Read about this and much more on this virtual tour of sharks.
