Dolphins are small-toothed cetaceans easily recognizable by their curved mouths, which give them a permanent “smile.” There are 36 dolphin species, found in every ocean. Most dolphins are live in the ocean or brackish waters along coastlines. There are a few species, however, like the South Asian river dolphin and the Amazon River dolphin, or boto, which live in freshwater streams and rivers.

The largest dolphin, the orca, can grow to be over 30 feet long. The smallest, the Maui dolphin, is just five feet long.

Dolphins feed chiefly on fish and squid, which they track using echolocation, built-in sonar that bounces sound waves off prey and reveals information like its location, size, and shape. An echolocating bottlenose dolphin can make up to a thousand clicking noises per second.

Behavior and reproduction
Living in pods that can number a dozen or more, dolphins are intensely social mammals that communicate with squeaks, whistles, and clicks. Whether dolphins have language, as humans do, is a topic that scientists have debated for decades.

As mammals, they have warm blood and nurse their young. Dolphins have more than one mate, and generally produce a single offspring that will stay with the mother for up to six years, depending on the species.

Dolphins are graceful, sleek swimmers that can reach speeds of more than 18 miles an hour. They are also playful and often frolic in a boat’s wake, leaping out of the water—possibly for fun, to communicate, or even shed pesky parasites.

Threats
For centuries, people have hunted dolphins for their meat and blubber. Today, their main threat comes from being caught accidentally in commercial fishing nets. Dolphins must rise regularly to the surface to breathe—becoming entangled in nets prevents this, leading to drowning. For Maine dolphins, warming ocean temperatures because of climate change have caused some of their primary food sources to move into deeper, cooler water. Furthermore, marine heatwaves, also caused by climate change, appear to have a negative effect on dolphins' reproductive rates and ability to survive.

In addition to hunting and entanglement in fishing gear, freshwater dolphins face the additional threat of dams fragmenting and degrading their habitat.
