Dolphins are really interesting mammals, especially when it comes to their interactions with humans.  They are incredibly friendly and trainable, so we can observe them and their behaviors.  The military uses them to find mines, many resorts that allow you to go swim and interact with them, and Sea World puts on dolphin shows.  They do amazing tricks.  Because they are so cooperative, humans have almost adopted them like pets in many scenarios, but they still mostly live in the wild.  Even those who haven’t been trained tend to be friendly to humans.

Fabulous Facts About Dolphins:

  • Dolphins are mammals, they breathe air, feed their young milk, are warm-blooded, and have hair on their bodies.
  • Dolphins make clicking and squealing noises to communicate.  You can approximate a dolphin’s whistles with a balloon by letting the air out slowly with the neck stretched.
  • Dolphins like humans and can be trained to do everything from tricks in an aquarium to carrying the mail for underwater research labs.  Some dolphins have been trained to swim with handicapped children.
  • Dolphins can stay underwater for fifteen minutes at a time.
  • If a dolphin gets sick or injured, other members of its family help it swim and get breaths of air until it can swim on its own.
  • Dolphins work together to protect the group from predators like sharks.
  • They use echolocation to find food.
  • Dolphins eat fish and squid.
