Over 400 species of sharks inhabit the waters of planet earth today. Perhaps the best known, most talked about,
most feared, is the Great White. With over 300 razor sharp teeth the Great White Shark has few to no equals.
When deep-water fish are caught a condition called barotrauma, expanding gases in the swim bladder, is more often than not fatal. A process called venting releases the gases. Venting a Great White could possibly be a 'little' on the dangerous side. NO PROBLEM! Sharks do not have a swim bladder. Instead of a swim bladder sharks have a large liver filled with low-density oil providing static lift. No venting necessary.
No Great White discussion would be complete without a close look at the movie JAWS.
On June 20, 1975, JAWS, s film directed by Steven Spielberg that made countless viewers afraid to go into the water, opened in theaters. The story of a Great White shark that terrorized a New England resort town became an instant blockbuster hit and, at well over 400 million dollars, one of the highest-grossing films in movie history:
