Just like humans, dolphins stay close to their families. Sometimes, if there is an abundance of food, multiple different pods come together to form a superpod, which can have over 1,000 members. Dolphins even have personalized whistles, which are like names. Studies show that orca pods even have their own “language” of clicks and whistles which they use to communicate (orcas are not actually whales, they are the largest type of dolphin). Parent dolphins sometimes punish young dolphins for misbehaving, and studies have shown that dolphins are some of the only animals who can actually recognize themselves in a mirror. “Not only that, but they also recognize changes in their appearance, showing a complex form of self awareness.” says onegreenplanet.org.
