paragraph on dolphin

Answer 1

Dolphins are mammals in the order Cetacea. They are part of the toothed whales. Generally, they are among the smaller whales. Most live in salt water oceans, but some live in rivers – there are oceanic dolphins and river dolphins. Dolphins are from 1.5 metres (4.9 ft) to 4 metres (13 ft) long, but the largest dolphin, the killer whale (or orca), can be up to 8 metres (26 ft) long.

The name 'dolphin' comes from the Ancient Greek δελφίς (delphis) meaning "with a womb", because it was first thought to be a fish with a womb. It is now known to be a mammal, and quite an intelligent mammal. Dolphins breathe air. A dolphin's nose is on top of its head so the dolphin can easily breathe on the surface of the water. The skin of a dolphin has no scales. It is soft and smooth. However, it is very firm, due to how much muscle they have. Dolphins use echolocation to find their food.
