There are actually 40species of dolphins, but the most common species is the Bottlenose.
Dolphins stay with their mothers for a long time; some stay up to eight years.
Dolphins are nurturing toward sick or injured animals in their pod.
Dolphins are very social animals and swim in groups called “pods.” Some pods can have up to 1,000 dolphins.
When dolphins sleep, only half of their brain sleeps at a time. This means one side of their brain stays “on” so they can breathe and stay alert.
Dolphins have around 100 teeth, but they’re not used for chewing. They use them like fish hooks to grab fish in the water, but then swallow them whole.
