The dolphin uses echolocation to find its prey
The friendly-looking dolphin is known for its intelligence and approachability. It has long fascinated researchers because of its social behaviour, and its large, highly developed brain. Its auditory cortex, in particular, is highly complex and allows for a hearing range between 30,000 and 160,000 hertz.
Dolphins are also quick at processing sounds, and use a technique called echolocation, which works like a biological sonar. Dolphins emit high-pitched noises and interpret the echoes bouncing off nearby objects to understand their environment. They use this skill to locate and identify nearby prey, even detecting creatures buried in sand. Dolphins also have intricate communication techniques, and can produce and discern a wide range of noises and vocalisations.
