Blue Penguins are one of the smallest of all penguins and are primarily found on the shorelines of New Zealand and Australia. Now, Yale University researchers and colleagues at the University of Akron have found that they utilize a novel method to express the color in their feathers.
In a recent study in the journal Biology Letters, the researchers found that the penguins owe their blue hue to the scattering of light caused by a densely-packed, side-by-side arrangement of nanofibers.
The nanofibers are so unusual that researchers speculated they could one day be used for purposes such as creating flexible electronics or as dressing for wounds.
Vinodkumar Saranathan, Richard Prum and Jakob Vinther were Yale authors of the study.
