To many, sharks symbolize the very essence of ruthlessness, representing the ultimate savages of the natural world. In this fascinating film, Oceanic Research Group takes a look at these animals in their own element, and attempts to discover the truth about sharks. Sharks have been swimming in the world's oceans for over 300 million years, making them older than the dinosaurs. Although they are frequently thought to be primitive fishes, they are in fact highly evolved. Sharks have excellent senses of smell and sight, as well as an ability to detect electrical fields generated by the swimming muscles of fish.
Sharks perform an important role in the ecosystem, at the top of the oceanic food chain.
A shortage of sharks could have devastating effects on the balance of the fragile ocean food chain. Therefore, they need to be protected from overfishing. This film discusses the taxonomy, anatomy, habits, and behavior of sharks, and features stunning, never-before seen film footage. Learn about the powerful senses of the shark, how it swims and hunts, and the truth about shark attacks. Shark lovers should also check out our Great White Shark poster .
