How does dolphin protect it self from danger?

Dolphins protect themselves by swimming in pods. Dolphins also take care of each other when one might be sick or injured. Dolphins help each other because they need to be strong as a group.

Additional Information: The Dolphin in general doesn't have many predators, outside of man. But there are a few natural marine predators, and young Dolphins are at risk, more so than adults. Dolphins use their pod numbers, and constant movement to confuse predators, plus the more eyes watching for predators the better. They will also use vocalizations, such as whistles, and clicks to warn others, once a predator is sighted. They have extremely good eyesight, are quick, agile swimmers, and will often flee a predator. But they are also fiercely protective of pod mates, and will defend the young or infirm of their pod. The Bottle-nose Dolphin is known for using an aggressive defense, usually against an attacking shark. They will use their nose to ram the shark, trying to batter the underbelly of the shark, making quick strikes with their snouts. While others try to distract the shark, smacking it with their tails, and darting in to land quick jabs, and dart back away. Most times the shark will swim away. Repeated blows to the sharks soft underbelly can cause serious internal trauma, and even death. For more details, please see the sites listed below.
