The playful dolphins enjoy riding the bow of fast moving vessels where they can be pushed by the wave and surf effortlessly. Most dolphins have a curved dorsal fins and a right and left ventral flipper that vary in size and shape from one species to the next. Their beaks are well defined and they all generally have conical teeth arranged in both the upper and lower jaw. Using a system of sonar similar to bats, dolphins are able to augment the amount of sound within their environment. The method of echolocation involves the dolphin's emission of short and repeated 'clicks' from the upper nasal passage, located in the rounded forehead, called the melon.
Echolocation informs the dolphin of the size, shape and movement of an object.
The clicks are reflected off any object and received back as echoes through the animal's lower jaw.
