Why Are Dolphins So Popular?
Posted on
A dolphin is an aquatic mammal. They belong to the families Delphinidae, Platanistidae, Lipotidae, and Iniidae. There are about 40 species currently extant. These mammals are found throughout the world, and are also called bottlenose dolphins. They are highly regarded for their playful and lovable personalities. In addition to their playful and social personalities, dolphins are also a great source of information about marine conservation.
Dolphins are extremely intelligent animals and are capable of identifying other creatures. Using the same principles as radar, dolphins use a series of ultrasonic sounds that are repeated 800 times per second. These sound pulses focus in a large lens-shaped organ on their melon. The sound pulses are then reflected back into the surrounding waters. This method allows dolphins to see and identify objects, even when they are not in the water.
