Eudyptes chrysocome (Rockhopper Penguin) is a species of birds in the family penguins. They are listed as vulnerable by IUCN. They are native to Atlantic Ocean and The Neotropics. They are diurnal carnivores. They have parental care (paternal care and female provides care). They rely on swimming, flight, and lift powered swimming to move around.

URI: http://eol.org/schema/terms/vulnerable
Definition: A taxon is Vulnerable when the best available evidence indicates that it meets any of the criteria A to E for Vulnerable, and it is therefore considered to be facing a high risk of extinction in the wild.

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.
