They can also move each eye independently of the other, providing even more range. They have strong eye muscles which can change the shape of their lens and allow them to focus both underwater and in the air. They secrete a mucus over their eyes which washes away debris. They also have an excellent sense of hearing. Sounds travel through their lower jaw to their inner ear.
Bottlenose dolphins communicate with each other using a collection of chirps, whistles, and clicks.

They create these sounds using nasal sacs in their heads and their blowholes. Each dolphin has a signature whistle used to identify itself.
When lost or isolated, a dolphin uses the signature whistle to call out to the group. They use these clicks in a sonar system called echolocation. When the clicking sound reaches an object, it bounces back to the dolphin as an echo. Dolphins can process this information to determine the shape, size, speed, distance, and location of the object.
Bottlenose dolphins use echolocation when hunting for fish, squid, and crustaceans. They have pairs of sharp, conical teeth on each side of their jaw, but they usually swallow their prey whole. They consume kg lbs. Although they sometimes hunt independently, they also cooperate in groups to capture prey. They take turns herding fish into smaller areas while others swim through and snap the fish up. Many times dolphins hunt in conjunction with fisherman, convening around fishing boats.

Very social animals, bottlenose dolphins generally swim in groups called pods of Offshore, they have been seen in larger groups of several hundred. These large groups are called herds. Within their groups, bottlenose dolphins like to play. They surf on waves near shore and ride waves caused by boats and big whales.
They have also been documented creating bubble rings with their blowholes, spinning them with their beaks, and then then breaking them apart by biting them. The technique of creating bubble rings is a learned behavior; dolphins watch others create them and then try to mimic the behavior.

Ultrasound images of pregnant dolphins show that at 9 weeks, the dolphin fetus starts swimming inside the womb. These images also reveal that dolphin fetuses develop hind limbs which later retract and disappear before the calf is born. These limbs served as a second set of flippers. Dolphins swim in the water but they are air breathers just like humans.
They need to resurface and use a blowhole at the top of their head for breathing purposes. Dolphins use echolocation to find the exact location and distance of objects, including their food.
Echolocation bounces off of the object and they can measure the distance by the amount of time it takes to bounce back or return to them. Dolphins do have excellent hearing and eyesight. Dolphins use a variety of sounds to communicate with each other including whistles, clicks and other noises. Scientists have spent years trying to see if they could figure out the communication and are still puzzled.

Dolphins often get caught in fishing nets set out by fishermen and many of the species are facing potential extinction. International organizations have banded together to protest that fishermen use special types of nets that allow the dolphins to escape. All rights reserved.
