Dolphins: smart, social, and full of surprises
Dolphins are more than just friendly faces in the sea. They’re incredibly intelligent animals that live in tight-knit groups, communicate in complex ways, and even have their own names.
Scientists are still discovering just how clever dolphins are, and the more we learn, the more fascinating they become.
How do dolphins talk?
Dolphins don’t speak like us, but they’re great communicators. They make clicking and whistling sounds to talk to each other. Each dolphin even has its own special whistle, a kind of name, that other dolphins recognise. Imagine shouting your best friend’s name underwater in the ocean. Do you think they could hear you?
They live in groups called pods, and they’re always chatting. Scientists believe dolphins share all kinds of messages, like where food is, when danger is nearby, or just saying, “Let’s go!”
Playing and working together
Dolphins love to have fun. They play games like chase and throw objects around to catch, even seaweed or jellyfish if they can’t find a ball floating around. It’s like an underwater game of tag and fetch.
Dolphins are also terrific at teamwork. They often hunt together, surrounding schools of fish, leaving them with nowhere to hide. In some places, dolphins have been known to work with humans, helping fishers by driving fish into nets, and then getting a tasty reward!
Some fin-tastic facts
- Baby dolphins are called calves, and they stay with their mothers for years to learn everything they need to know.
- Dolphins sleep with one eye open! They rest one half of their brain at a time so they can keep swimming and stay safe.
- There are over 40 different types of dolphins, including the orca, or killer whale, which is actually the biggest dolphin!
- Dolphins can swim up to 60 km/h (about as fast as a car in a city).
