A fish with a womb
The Bottlenose Dolphin (Tursiops truncatus) is the most common species of dolphin, inhabiting warm and temperate seas worldwide. The world dolphin is adapted from the word delphis, which means 'a fish with a womb'.
Dolphins are mammals, not fish. They are highly social, friendly and playful, and are believed to be the most intelligent of all animals.
Dolphins communicate with each other using sound, vision, touch and taste. However, they do not have a sense of smell. Their search for food is aided by echolocation.
They are carnivores and eat mostly fish and squid.
Your chances of seeing one in the wild
Pretty high. Though it depends which species.
According to an international group of experts at IUCN - The World Conservation Union, some species of dolphins are so endangered they could vanish within a decade.
The species on the brink include river dolphins like the Ganges River dolphin and Indus River dolphin. They face some of the most severe risks and are unlikely to survive unless we work effectively to save and conserve their environments.
