Our ocean is a big, blue world full of amazing creatures! From tiny plankton to colorful clownfish, and even giant whales and sharks, there’s so much to see. But today, let’s dive into the world of one of the cutest and smartest sea animals—dolphins!
There are 38 different kinds of dolphins. Most of them live in the ocean, but some, like the Amazon River dolphin, live in rivers. Dolphins are special because they are mammals. This means they are warm-blooded, and mother dolphins feed their babies with milk.
Even though most mammals have hair or fur, adult dolphins are smooth and hairless. However, baby dolphins are born with tiny whiskers around their noses, which they lose as they grow up. Dolphins breathe air using lungs, just like we do, and they have to come up to the surface to breathe through a special hole on top of their heads called a blowhole.
Dolphins have bones inside their bodies, making them vertebrates. They also have well-developed systems for breathing, circulating blood, and digesting food. Their sleek bodies, fins, and strong tails help them swim fast and gracefully through the water.
Dolphins are great hunters! They eat fish, squid, and shrimp. To find their food, dolphins use a cool trick called echolocation. They make sounds that bounce off objects and come back to them. This helps dolphins “see” with sound, even in the dark or murky water, to find their next meal.
Dolphins have a special way of blending in with their surroundings called countershading. They are darker on top and lighter underneath, which helps them hide from predators. Dolphins like to hang out in groups called pods. A pod can have just a few dolphins or even up to a thousand! Living in pods helps dolphins protect each other, especially the young ones.
Dolphins are very smart and can solve problems and communicate with each other. They work together to catch food and keep each other safe. Being in a pod is like being part of a big family!
Now you know all about dolphins, the ocean’s clever and adorable creatures. If you have any questions, feel free to ask. Thanks for learning about dolphins with us!
Sound Exploration: Try to experience echolocation like dolphins do! With a friend or family member, play a game of “Sound Tag.” One person closes their eyes and makes a sound, like clapping or tapping a surface. The other person listens carefully to figure out where the sound is coming from and tries to tag the sound maker. Switch roles and see how well you can “see” with your ears!
Dolphin Pod Role Play: Gather a group of friends or family members and pretend to be a pod of dolphins. Decide who will be the leader, the lookout, and the playful young dolphins. Move around your space like a pod, communicating with clicks and whistles. Discuss how working together helps dolphins stay safe and find food.
Observe and Draw: Visit a local aquarium or watch a documentary about dolphins. Pay attention to how they move, communicate, and interact with each other. Draw a picture of a dolphin in its natural habitat, showing its countershading and how it might look in a pod. Share your drawing and explain what you learned about dolphin behavior and their environment.

[Music] A worksheet related to this video can be found in the link below. Our ocean is filled with a great diversity of marine life, from microscopic plankton and clownfish to relaxed sea turtles and marine giants like sharks and whales. [Music]
Perhaps the cutest and one of the smartest marine animals are dolphins. There are 38 species of dolphins, most of which live in the ocean, but a few species, like the Amazon River dolphin, live in freshwater. Dolphins are mammals, which means they are warm-blooded and females nurture their young with milk. [Music]
You may recall that another characteristic of mammals is a body covered in fur or hair. Although adult dolphins are hairless, many newborn dolphins have a few whiskers around their snout when they are first born and lose them as they mature. As mammals, dolphins also get the oxygen they need using lungs and must come to the surface regularly to take in air. This is done through an opening on the top of their head called a blowhole. [Music]
Dolphins are vertebrates and have an internal skeleton made of bone. They also have a well-developed circulatory, respiratory, and digestive system. [Music]
Dolphins are well adapted to life in water. They have sleek, streamlined bodies, which, combined with fins and a powerful tail, allow them to move around effortlessly and with great speed. All dolphins are active predators, feeding on a variety of fish, squid, and crustaceans such as shrimp. Many dolphins locate their prey using a special technique called echolocation. They produce short pulses of sound that are reflected off prey and back to the dolphin. Dolphins interpret the reflected sound to determine the shape, size, speed, distance, and direction of travel of their unsuspecting prey, even at night or in murky water. [Music]
Dolphins exhibit a type of camouflage called countershading, whereby they are darker on the top and lighter on their underside. This makes them difficult to spot from above and below. Dolphins in groups are called pods. A pod can consist of as few as five to ten dolphins or as many as a thousand. Dolphins are capable of complex problem-solving and social interaction, and they communicate and work together in diverse ways to group up and catch prey. Living in pods helps to protect young dolphins as they mature. [Music]
So there you have it—all you need to know about the ocean’s smartest and cutest animals. If you have any questions, leave them in the comments below. Thanks for learning! [Music] Don’t forget to subscribe.
