Bottlenose dolphins are a very intelligent mammal. They can communicate with each other using echolocation. They make a maximum of 1,000 clicking noises per second. Those sounds will travel underwater and will reflect off of objects and into another dolphin’s ear. That sound allows the dolphins that heard it to know the size, shape, and location of the sender.

Dolphins are excellent swimmers and can do many tricks. They are often featured on shows in aquariums. When swimming, they can go at speeds of almost 30 kilometers an hour, 28.9 to be exact. They come up to breathe two or three times every minute. When dolphins jump out, they can reach 1.8 meters and land back in the water.

Dolphins can be found in tropical oceans. They eat fish lying at the bottom of the water and they also eat squids and shrimps. A long time ago, they used to be hunted to eat and for their oil, but now this rarely happens. Dolphins can easily be entangled in plastic bags, nets, ropes, and other waste found in oceans.
