Atlantic_spotted_dolphin_(Stenella_frontalis)_NOAADolphins are both very similar to humans and very different. We have long regarded dolphins as some of the most intelligent animals, and they’re highly social. They live in family groups, like humans do, and they even communicate with each other through a series of clicks and squeals that make up their own “language.” Some scientists even specialize in trying to learn what dolphins are “saying” to each other.
Even though we have a lot in common with dolphins, there are some big differences. For instance, while dolphins are mammals like us, their aquatic lifestyle means that they do a lot of things differently, including breathing and sleeping. When they sleep, dolphins float on one side and keep one eye open. And to breathe, dolphins take in air through their blowholes when they surface, and then seal up their blowholes when they’re swimming—like how we hold our noses when we go underwater! What other similarities and differences can you and your family find between humans and dolphins?
