Amazon Milk Frogs, also known as Mission Golden-eyed Tree Frogs or Blue Milk Frogs, were first found in Rio de Janeiro's Maracanã River. The name "Milk Frog" refers to the poisonous, white, milky secretion that this frog secretes when threatened. But what about that blue mouth? This species is most active at night and is known for its loud vocalizations.

People may unsuspectingly choose friends who have some DNA sequences in common with them, a new analysis finds.

Researchers compared gene variations between nearly 2,000 people who were not biologically related, and found that friends had more gene variations in common than strangers.

The study lends a possible scientific backing for the well-worn clichés, "We're just like family," or "Friends are the family you choose," the researchers said.

"Humans are unique in that we create long-term connections with people of our species," said Nicholas Christakis, a social scientist at Yale University involved in the study. "Why do we do that? Why do we make friends? Not only that, we prefer the company of people we resemble."
