Scientists often remind us just how weird and wonderful our world can be. Take a quick look at some of the strangest discoveries of 2015.
1. FANGS AREN’T THE ONLY STRANGE THING ABOUT THESE FROGS
A newly discovered species of fanged frog does what no other frog can do—give birth to live tadpoles instead of laying eggs.
“Almost all frogs in the world—more than 6,000 species—have external fertilization, where the male grips the female in amplexus and releases sperm as the eggs are released by the female,” says Jim McGuire, associate professor of integrative biology at the University of California, Berkeley.
“But there are lots of weird modifications to this standard mode of mating. This new frog is one of only 10 or 12 species that has evolved internal fertilization, and of those, it is the only one that gives birth to tadpoles as opposed to froglets or laying fertilized eggs.”
