Hungry penguins with tiny video cameras strapped to their backs have given scientists a rare glimpse of their spectacular and voracious feeding habits.

Footage from Adélie penguins in waters off the coast of Antarctica showed the birds darting at krill, snapping up fish, and hunting down prey beneath sheets of floating ice in the Lützow-Holm bay area.

In more than 14 hours of film captured from 11 birds, not once did a penguin miss its target. Some marine creatures had no time to hide, while others tried to flee and failed.

One penguin swam into a dense swarm of krill and captured two of the shrimp-like creatures in one second. Another penguin encountered a school of what appeared to be Antarctic silver fish and caught 14 in 20 seconds. In many cases, the moment the penguin captures its prey is only clear when the video is slowed down
