them survive in the ocean. Such as, dolphins are mammals and breathe air like humans. This is why they have a blow hole on their back, so they can swim to the surface of the water to breath two times a minute. Dolphins also have a unique way of hunting for fish. They use echolocation to send out bursts of sounds which reflects off of objects in the water. These sounds come back to the dolphin’s which allows them to easily locate their prey. They not only make sounds for echolocation, but the dolphins often make loud whistling noises as a way to communicate with other dolphins. Dolphins are a very intelligent species. They have a great memory and can be easily trained. Dolphins have been used to preform shows in aquariums, and were once used as mailmen to deliver mail to underwater labs in the ocean. They are not only smart and sociable, they are also very protective of their pods and baby dolphins. When dolphins detect sharks or other predators nearby, they confront the predator and circle around it till it gets scared and swims away. Dolphins have many different adaptations that help them survive within their environment. They use these adaptations to breath, detect food, communicate, and defend themselves. Without one of these adaptations it would be very difficult for a species like dolphins to survive in their environment.
