Sand Tigers - As Seen of the Discovery Channel
Deep beneath the turbulent waters known by sailors as the "Graveyard of the Atlantic" lurks an extraordinary creature. Mysteriously attracted by the eerie bulk of a shipwrecked submarine, they gather in enormous numbers, engaging in mating rituals so vigorous that males' teeth are actually broken off. But, the Sand Tiger Shark's unusual breeding behaviour is only the beginning of its fight for survival. Because, as researchers recently discovered, prenatal Sand Tigers have evolved a shockingly effective mechanism for eliminating competition: While still inside its mother's body, the largest shark pup will consume all of its fetal brothers and sisters.
Now, descend into the treacherous, tide-swept waters off Cape Hatteras to visit the site of the sunken Navy submarine Tarpon and its attendant population of docile, diver-friendly Sand Tigers. Share the elation of shark experts as they confirm that the sub is actually a rare breeding ground for the swarming sharks. Join scientists who capture live Sand Tigers and, for the first time, attempt to observe the bizarre phenomenon of fetal shark "interuterine cannibalism." And witness the desperate efforts of conservationists fighting to keep muderously efficient shark fishing fleets from totally decimating the vunerable spawning grounds of the strange but marvelously adapted creature.
