The species of the shark in the original "Jaws" movie is a) Great White Shark. Sharks are fascinating cartilaginous fish with powerful jaws and multiple rows of sharp teeth that can tear into their prey. A Great White Shark's diet typically includes fish, seals, and even other sharks, and their teeth are well-adapted for cutting into large prey.
