Dolphins

Dolphins are marine mammals that are closely realted to whales and porpoises. There are almost forty species of dolphins in the world in the seventeen generation!They can be from 1.2 metres (which is 4 ft) and 40 kilograms up to 9.5 metres(which is 30 ft!)and 10 tonnes. They are found worldwide, usually in shallow seas. They are also carnivores,mostly eating fish and squid. Dolphins are considered the most intelligent animal and their often playful and friendly appearance have made them popular in human culture.
Dolphins can see in both land and sea,and their sense of hearing is superior to that of humans.They have also been known to seemingly protect swimmers from sharks by swimming circles around the swimmers or charging the sharks to make them go away.Dolphins also show cultural behaviour, something long believed to be a quality unique to humans.
Dolphins have few natural enemies, some species or specific populations having none at all making them apex predators. For most smaller species of dolphins, only a few larger species of sharks such as the bull shark, dusky shark, tiger shark and great white shark are potential risks, especially for calves. Some of the larger dolphin species such as Orcas may also prey on some of the smaller dolphin species, but this is rare. Dolphins may also suffer from a great variety of diseases and parasites. Thats why, marine lovers, appreciate our marine animals when we can!:)
