Known for their empathy and playfulness, dolphins also have one of the most advanced communication systems among all animals. Starting from birth, they develop a complicated language of squawks, whistles, clicks, and squeaks. They even communicate nonverbally through body postures, jaw claps, bubble blowing, and fin caresses.
With brains that are about 25 percent larger than a human’s, dolphins can also reason, problem-solve, and comprehend ideas. New studies show they may even be mathematicians. Scientists report that these bright mammals likely use nonlinear math formulas when catching predators. Dolphins blow bubbles that vary in exact amplitudes to detect fish, and then are able to subtract values found with their echolocation to confirm the target.
