Because dolphins breathe atmospheric air, they cannot afford long periods of sleep underwater. They have adapted to aquatic life by taking 15-20 minute naps during which only one hemisphere of the brain sleeps. During this nap, the dolphin can swim, breathe and look out for danger. 1)


Dolphins use echolocation and this is how they find their way in the surrounding environment. By emitting high-frequency sounds, they listen for the echoes that come back to them and build a “map” of the space based on these sounds. They also use echolocation to find food and hunt. 2)


Dolphins hunt in packs and feed on fish, squid, and shellfish. 3)


Orcas are the largest natural enemies of dolphins. Although they themselves belong to the dolphin family, this does not stop them from hunting their smaller cousins. 4)


Dolphins communicate both verbally and non-verbally. They can communicate through their tail movements, the way they swim, or the way they strike certain poses. In addition, they have a rich language consisting of special high-frequency clicks and whistles. By means of sounds, they can inform each other of danger, show their emotional state or call younger, unruly dolphins to order. 5)
