Dolphin Facts for Kids

What are dolphins?

Dolphins are cetacea marine mammals.  There are 36 species of dolphins, 32 types of ocean dolphins, and four types of river dolphins. A female dolphin is called a cow. A male dolphin is called a bull. A baby dolphin is called a calf.

Where do dolphins live?

Dolphins can be seen all over the world. They live close to the coastline in all the oceans on the planet. They live in freshwater rivers of Asia and South America. Some dolphins live in the Amazon River.

What do dolphins eat?

Dolphins have two stomach parts. One stores food, and the other digests the food. Dolphins have 100 teeth! Let’s find out what they like to eat.

Dolphins have a diverse and interesting diet, just like us! They eat different kinds of food depending on where they live and the type of dolphin they are.

Some dolphins are called “fish eaters.” They love to gobble up fish like herring, mackerel, and anchovies. These fast swimmers use their sharp teeth to catch and eat their favorite fishy treats.

But that’s not all! Other dolphins, called “carnivores,” eat more than just fish. They also enjoy munching on squid and octopus. These are slippery and slimy creatures that live in the ocean.

Here’s something fascinating: Some dolphins are known as “ocean hunters.” They work together as a team to hunt for food. They might surround a school of fish and take turns diving in to catch their meal. It’s like a dolphin dinner party!

Dolphins also like to eat shrimp and crab, which are small crustaceans that live at the bottom of the ocean floor.

Dolphins cannot chew with their teeth.  This is because they do not have jaw muscles to help chew.  Dolphins eat by swallowing their food whole.

Dolphins eat about 5% of their body weight daily.

There are many more types of dolphins out there, each with its own special characteristics and habitats.

The Bottlenose Dolphin, which is one of the most well-known dolphins. They have a sleek body and a cute little snout that looks like a bottle, which is where their name comes from.

Dolphins use echolocation to find food and navigate.  Echolocation is determining location by high pitch sounds. Let’s explore this further.

Echolocation is like using sound to “see” your surroundings. When dolphins want to find objects or other animals in the water, they make a special sound called clicks by blowing air out of their blowhole.

These clicks travel through the water and bounce off objects like a ball bouncing off a wall. When the sound bounces back to the dolphin, it creates echoes.

The amazing part is that dolphins can listen very carefully to these echoes.

They can tell how long the echoes take to come back and how loud they are. Dolphins can figure out the size, shape, and distance of objects around them by paying attention to these echoes.

It’s almost like they create a mental map of their environment using sound!

 Bats also use echolocation.
