Greg Lasley cc-by-nc-4.0

Aethia cristatella (Crested Auklet) is a species of birds in the family auks. They are native to The Nearctic and the Palearctic. They are diurnal carnivores. They have parental care (female provides care and paternal care). They rely on flight and lift powered swimming to move around.

URI: https://eol.org/schema/terms/lift_based_swimming
Definition: Hydrofoils, or fins, are used to push against the water to create a normal force to provide thrust, propelling the animal through water. The reduction of fin cross-sectional area helps to minimize drag, and therefore increase efficiency. Regardless of size of the animal, at any particular speed, maximum possible lift is proportional to (wing area) x (speed)<sup>2</sup>. Dolphins and whales have large, horizontal caudal hydrofoils, while many fish and sharks have vertical caudal hydrofoils.
