根据下面的海洋生物信息，我需要关于大白鲨的基本介绍：英文总结的字数应当在50字以内，并且整个文本应当在不包含任何分隔符号。

Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, several rows of teeth, and five to seven gill slits on the sides of the head. The great white shark, Carcharodon carcharias, an Apex predator, is among the major natural predators of marine mammals and large fish. 

Great white sharks inhabit mainly in cool waters around the world. They are solitary hunters and exhibit a unique hunting technique known as "sneak attack." Normally, they are not very social, though they live in the same area as other sharks and marine creatures. 

Biologically, great white sharks are separated from other sharks by their large size and peculiar triangular teeth. Mature great white sharks typically grow up to 20 feet long and weigh around 5,000 pounds. They can coast along for hours without tiring, hence their nickname, "the living torpedo."
