Abstaining Blue Footed Boobies Get Sexier (VIDEO)

Now this is a new angle on abstinence, at least, in the kingdom. Male blue-footed boobies who abstain from sex for a year develop a brighter, more attractive shade of blue in their feet.

From our friends at National Geographic:

A new study shows that while attractiveness of the blue feet diminishes with age in males that reproduce each year, if males skip a breeding season and dont mate, they displayed a more attractive foot color and had more green chroma....

They concluded that its likely the sabbaticals from reproducing offspring may allow the male boobies to physically recover and display brighter feet in their quest in finding a mate.
