Dolphin behaviour explained
This behaviour involves a dolphin alternating between being underwater and flying through the air. The dolphin leaves and enters the water headfirst, which helps the animal move quickly without constantly battling water resistance.
Dolphins sometimes pop up vertically headfirst out of the water before then bobbing back down again. This behaviour gives the dolphin a good look around at what’s going on, and the animal may even do this to get a better look at the humans watching it.
This entails leaving the water completely and landing with a splash. This behaviour may help scratch an itch, dislodge parasites or accelerate a dolphin’s natural skin exfoliation. On the other hand, maybe it’s just brilliant fun. Nobody knows for sure.
Dolphins seem to enjoy swimming in the pressure wave created by a moving vessel. This disturbed water may be easier for the dolphins to travel through, therefore reducing the amount of effort that is required for them to move forwards.
As the name suggests, this behaviour involves a dolphin beating its tail on the water’s surface. This could have a communicative purpose, but some dolphin species use this method to stun nearby fish to make them easier to catch.
