The bottlenose dolphin is a smart sea animal.
These animals use sound to find things. They make clicking sounds in the water. The sounds bounce off objects and come back. This helps them find food.
Dolphins can also use tools. Some use sponges to find food. They are very smart and can learn many things. 
They have a long snout. This snout helps give them their name. They can jump high in the air. Most dolphins live for more than 40 years.
The bottlenose dolphin is a smart whale.
Dolphins are very clever. They can use tools like sea sponges to find food. Scientists study how they learn and use language. Some dolphins even work with humans. The military trains them to find sea mines. 
These animals use sound to see. This way of seeing is called echolocation. The dolphin makes clicking sounds. These sounds hit objects and bounce back as echoes. This helps them know the size and shape of things.
Dolphins have a long snout called a rostrum. They also have a blowhole on top of their head to breathe. They move through the water by moving their tail lobes. These lobes are called flukes. Their skin uses countershading to hide. This means they are dark on top and light on the bottom. Most dolphins live for more than 40 years. 
The bottlenose dolphin is a smart, toothed whale. 
Dolphins have many ways to interact with their world. They use a special way of seeing called echolocation. The dolphin sends out clicking sounds in a beam in front of it. These sounds hit objects like rocks or fish and bounce back. The dolphin listens to these echoes through its lower jaw. This helps the dolphin make a sound picture of its target. Echolocation tells them the size, speed, and distance of an object.
Humans and dolphins have a long history of meeting. Some dolphins are famous from television shows like Flipper. Because they are so smart, people have trained them for jobs. The military uses them to find sea mines or divers. 
Dolphins have very interesting bodies that help them swim. They have a long snout called a rostrum. On top of their head, they have a blowhole to breathe. To move, they move their tail lobes, called flukes, up and down. They use side fins, called pectoral flippers, to steer. 
You might recognize dolphins from many different places. You may have seen them in aquarium shows. Some special hybrids, like the wholphin, live in places like Hawaii. 
The bottlenose dolphin is a highly intelligent toothed whale. It belongs to the genus Tursiops. These animals are members of the Delphinidae family, which includes oceanic dolphins. They are cosmopolitan, meaning they are found in many different parts of the world. They inhabit warm and temperate seas across the globe. You will find them almost everywhere except for the Arctic and Antarctic Circle regions.
Scientists use complex methods to study these animals. They look at morphology, which is the physical shape and structure of the body. They also use molecular genetics to study DNA. In the late 20th century, combining these two methods helped solve many mysteries. Researchers can now see how different populations are related. This work helps us understand the different species within the Tursiops genus. 
There are several distinct species within this group. The common bottlenose dolphin is Tursiops truncatus. It lives in coastal and oceanic habitats in tropical and temperate oceans. The Indo-Pacific bottlenose dolphin is Tursiops aduncus. It lives in coastal waters near India, Australia, and Africa. In 2011, scientists described a third species called the Burrunan dolphin. This species lives in the lakes of Victoria, Australia. Some researchers also study Lahille's bottlenose dolphin in South America.
Bottlenose dolphins possess remarkable biological tools. They use echolocation to navigate and find food. This is a form of sonar. The dolphin emits clicking sounds in a focused beam. These sounds hit objects like fish or rocks. The sounds then bounce back as echoes. The dolphin receives these echoes through its lower jaw. This allows them to form an "echoic image" or a sound picture. This picture reveals the shape, size, and speed of an object.
Their physical bodies are built for life in the sea. They have a long snout called a rostrum. Their actual nose is the blowhole on top of their head. To move, they use flukes, which are the lobes of their tail. They also have pectoral flippers for steering. These flippers contain bones similar to the limbs of land mammals. Their skin often shows countershading. This is a form of camouflage where the back is dark and the sides are light. 
Intelligence is a major part of their lives. They have a high encephalization quotient of 5.26. This number is even higher than that of chimpanzees. This likely contributes to their smart behavior. They can use tools, such as marine sponges, to find food. They also transmit cultural knowledge to their young. This intelligence has led to many interactions with humans. Some dolphins work with militaries to find sea mines. Others cooperate with fishermen to drive fish into nets. 
Humans also interact with dolphins in other ways. Some people watch them in aquarium shows. Others have seen them on television shows like Flipper. However, some human activities are harmful. Dolphins are sometimes hunted for food. They can also be killed as bycatch in tuna fishing. They might also get caught in crab traps. We must understand these animals to help protect them.
Sometimes, different dolphin species mate to create hybrids. One famous example is the wholphin. This is a hybrid between a bottlenose dolphin and a false killer whale. These hybrids can be fertile. They can be found in the wild and in captivity.
