Life of a Bottle-Nosed Dolphin
The Bottle-nosed Dolphin is the most studied and generally the best-known species of dolphin. Bottle-nosed dolphins are classified "Tursiops truncates" in scientific name, and belong to the family Delphinidae. The dolphin is a very intelligent individual. Bottle-nosed dolphins are commonly found in zoos or marine parks because of their capability to perform tricks. They can jump through hoops 5 meters high because of their incredibly powerful tail. As well as jumping, Bottle-nosed dolphins can raise themselves upright out of the water and travel backwards, by threshing their tails. Bottle-nosed dolphins are generally coastal creatures, occurring along almost all tropical and temperate coasts, although they are also found offshore. In addition, the Bottle-nosed dolphin is called the "all-ocean" dolphin, meaning that it lives in every ocean. It is common for a school of 20 dolphins to live together in coastal regions, but school of 200 dolphins are found in the offshore places. These schools don't seem to have a leader and generally stay together for life. Dolphins eat food such as shrimp, squid, small sharks, other vertebrates and fish. When they find a large school of fish, several schools o
A Bottle-nosed dolphins have an acute vision both in and out of the water. They have a highly developed light-reflecting layer that reflects light through the retina a second time, giving Bottle-nosed dolphins enhanced vision in dim light. Although it is not confirmed, rods and cones have been found in their retina, giving the question weather or not they can see color. Other senses such as taste, smell and touch, are still to be questioned but through observations and behavior, it is believed that they have a well-developed senses of touch. Bottle-nosed dolphins rarely fight with each other because there is no power to be gained by it. They communicate by means of whistles and rasping sounds. Also, the use of echolocation is practiced, which is sending high-frequency clicks that bounce off prey and other objects and use the returning echoes to identify the objects. Bottle-nosed dolphins have been known to swim with ships for food, which is a common occurrence for cruise ships. As for migration, this dolphin can live in any ocean it wishes to, except the Antarctic seas, but commonly sticks to the same oceans or sea for its entire life. Bottle-nosed dolphins have great hearing capabilities, just as well because they use it like we use the power of speech. For example, they have a highly developed auditory cortex of the brain, with the auditory nerve carrying 67,900 cochlear fibers, which is twice as much as normal humans. Bottle-nosed dolphins respond to tones within the frequency range of 1 to 150 kHz (average hearing range for humans is about .02 to 17 kHz.) The reason why they have great hearing is because of thei
