Dolphins are known to defend themselves against sharks and have been observed to chase them away in the wild. In some cases, dolphins have been known to injure or even kill sharks in self-defense or during competition for food. It is not common for dolphins to actively seek out and kill sharks as their primary source of food.
Moose mark their territory by rubbing their antlers against trees to leave scent from glands located near their eyes, as well as by urinating and defecating in specific areas to establish their presence to other moose. They also make vocal calls to communicate and defend their territory.
Any body who's ever watched Flipper knows that most sharks are leary of dolphins and porpoises. They can out swim sharks and ram them with their 'beaks'. This may not apply to the Great White Shark who is pretty impressive swimmer in its own right.
