Dolphins hear when the sounds in the water bounce off the dolphin's jaw bone into the middle ear. Dolphins can hear far better than humans and their hearing is even better than that of dogs.Know More
The process of hearing in this way is called echolocation. Dolphins send sound waves through the water using their foreheads. When the sounds bounce off objects, they create echos that get sent back to the dolphins. They feel the echos bouncing off their jaws and every creature gives off a different type of echo. These echos help a dolphin determine what kind of object is around and the dolphin can determine how far away an abject is by the strength of the echo.
Dolphins don't have a sense of smell, so they have to rely on hearing and sight to help them avoid predators and find food. They also have to be able to hear the communication of other dolphins in the water.
Dolphins produce a variety of different sounds as a form of communication. They use moans, clicks, whistles, and squeaks to communicate. They can hear sounds of up to 150 kHz while humans can hear sounds up to 20 kHz so despite the fact that they don't hear in the same way as humans, their hearing is far superior.Learn more about Marine Life
Dolphins do not mate for life. A pair of dolphins typically engages in mating for a few days, but then the male goes on to mate with other females.Full Answer >
Some dolphins migrate seasonally to warmer water, but other dolphin pods will remain within a home base without migrating. Scientists differentiate between coastal dolphins and off-shore dolphins. Coastal dolphins are more likely to migrate than off-shore dolphins, which scientists attribute to the coastal dolphin's smaller body needing warmer waters.Full Answer >
A dolphin's slimmer body, beak-like nose and curved fins distinguish it from the porpoise's stout build, rounded face and triangular fins, according to the National Ocean Service. Although they are different species, dolphins and porpoises both belong to order Cetacea. Approximately 32 dolphin species have been discovered, while only six known porpoise species exist.Full Answer >
All dolphins have conical teeth that are used for biting and trapping prey, such as crustaceans and fish, but are not used for chewing. Dolphins swallow their prey whole. Dolphins fall into the odontoceti, or "toothed whale," suborder of cetaceans, the order that includes all whales, dolphins and porpoises.Full Answer >
