The behavior may seem like a strange sight - but as it turns out, this isn't such a rare occurrence. Naomi Rose, a marine mammal scientist with the Animal Welfare Institute, told The Dodo that this behavior isn't unusual at all.
"Pacific white-sides are very acrobatic," she said in an email. "What you see here is a form of breaching – they come out of the water full-body and may do several in a row, as this animal did."
The behavior is similar to porpoising, during which an animal jumps out of the water right side up and moving forward. Porpoising allows the dolphin to move quickly with less hydrodynamic drag.
