Centuries ago, when penguins were first encountered by European explorers, they were not thought to be birds but rather a fish-like relative. Subsequent accumulation of knowledge has shown penguins to be an avian species with unrivaled aquatic attributes, owing to a number of evolutionary adaptations: shape change, low drag, ability to regulate buoyancy, and extraordinary surface compliancy from their featheration. They are indeed the most extremely specialized diving bird, having given up flight (which otherwise is hugely advantageous) to the benefit of underwater prowess (such as speed, maneuverability and an ability to exploit an extraordinary range of depths). This flightlessness, however, also comes with costs that are substantial for a seabird (such as the inability to cover large distances quickly in reaction to ephemeral prey); and the energy needed to cope with moving through an aqueous environment, which is more resistant than air. For penguins, the high energetic costs inexploiting the ocean environment thus makes them especially sensitive to changes in food availability or their access to their prey.
