Dolphins are highly intelligent aquatic mammals that are closely related to whales and porpoises. They are found in all the world’s oceans, from the cold waters of the Arctic to the warm waters of the tropics. Dolphins live in pods (groups) of up to several hundred individuals, but some species, like the bottlenose dolphin, live in much smaller groups or even alone.
Dolphins communicate using a variety of sounds and gestures, and they have been known to work together to solve problems. Some species of dolphins are known to use tools, such as sponges used by bottlenose dolphins to protect their noses while foraging for food on the seafloor.
Dolphins are very social animals, and they have been known to help humans in need. For example, there have been reports of dolphins rescuing swimmers from sharks or helping fishermen herd fish into their nets. Dolphins also seem to enjoy human contact and will often approach boats or swim alongside people in the water.
Despite their friendly nature towards humans, dolphins are wild animals and should not be treated as pets. Wild dolphins should only be observed from a distance so as not to disturb them or interfere with their natural behavior.
