Most species of Shark are successful predators. Thier Class -- Chondricthyes -- are cartilaginous fish, so they lack the strong, more rigid, (usually) calcium based skeletons of the Teleostes, or boney fishes, which are phylogenically (and evolutionarily) more modern. So sharks are typically more easily damaged than bony fish. However, sharks have a wide niche, a viable birthrate, are present in every ocean and even in some lakes and rivers. As such, I think it's fair to say they're very effective and successful predators.
