TOKYO (AFP) - Miniature cameras attached to a penguin's head have given Japanese scientists a bird's eye view of the creature's incredible underwater hunting skills, the lead researcher said Tuesday.
Using video cameras weighing just 33g and equipped with accelerometers, depth gauges and thermometres, researchers were able to see exactly what the Adelie penguin sees when it goes out to catch krill and other prey in its native Antarctica.
Mr Yuuki Watanabe, of the National Institute of Polar Research in Tokyo, said the team was amazed to discover that the bird adapts its hunting behaviour depending on what it is trying to snare.
