When you go on dolphin excursions, you’ll likely observe the friendly creatures interacting with each other, but you may not be sure how they do it. Dolphins have developed a complex system of sounds and body language to relay ideas and feelings. The next time you see them, perhaps you can figure out what they’re saying.

How Do Dolphins Talk to Each Other?

To communicate with each other through sounds, dolphins whistle, click, or hold out sustained tones. When they’re feeling excited, upset, or aggressive, they may create an oscillating noise. They’ll let out a loud burst of sound when they want to play. Each dolphin has their own pitch, which allows them to distinguish speakers from each other.

They also communicate physically. For example, their famous jumping indicates playfulness. A gentle bump is a sign of friendship or affection, as is touching fins with another dolphin. To display aggression, they’ll bump harder, posture in the shape of an S, spread their fins and jaws wide, or slap their fins or tail against the surface of the water. If you see such behavior while on a dolphin excursion, keep a safe distance.

Can Humans Communicate With Dolphins Too?

Although scientists have been studying dolphins’ communication methods, they still don’t understand the reasons behind everything they do and haven’t developed a way to speak the dolphins’ language. However, the dolphins may try to interact with you when you see them. You’ll need to remain a respectful distance away, but if you appear non-threatening and keep your hands clasped or folded, they may come closer as a sign that they’re interested in being friendly. They tend to feel more comfortable with people in snorkeling gear rather than diving equipment, so combining dolphin excursions with snorkeling tours may be the best way to find out for yourself what it’s like to communicate with them.
