Dolphins are one of the cutest and most intelligent animals in the world. These mammals are generally found in oceans, rivers, and other water bodies.

Dolphins are very friendly with humans and share a great bond, they love to play on the surface of the water.

Dolphins are noisy animals and they communicate by whistling. Certain special species are called cetaceans, these are dolphin species that are known to live for 70 years and can weigh up to 170 tons.
