Five Dolphin Species and Where They Live

There are almost 40 species of dolphins. Six of them live in rivers rather than in oceans - which is interesting in itself.

However, this article is going to concern itself with the oceanic dolphins. We'll start with five this Sunday, and carry on with five more next Saturday.

Where do they live?

Long beaked and short beaked common dolphins: Abundant in the western Mediterranean Sea until the 1960s

Bottle-nosed dolphins
: When people think of a "dolphin", it is typically the bottle-nosed dolphin that they picture. "Flipper" was a bottle-nosed. It inhabits temperate and tropical oceans throughout the world. They don't inhabit polar waters.

Northern rightwhale dolphin: found in the Pacific.
Southern rightwhale dolphine: Southern right whale dolphins (the only dolphins without dorsal fins in the southern hemisphere) live in subtropical to subantarctic oceans of the southern hemisphere. Large populations are recorded off the western coasts of South America, where they are targeted by whaling operations; and off the coast of New Zealand

Tucuxi: Despite being classified as an oceanic dolphin, the Tucuxi lives in the rivers of the Amazon Basin!

Here's a project! Do some research to find out why a dolphin that lives in the rivers of the Amazon Basin is classified as an Oceanic Dolphin instead of as a River Dolphin!
