How the devil ray got its horns. If you ever find yourself staring down a manta ray, you'll probably notice two things right away: its massive fins and the two fleshy growths curling out of its head that give it the nickname 'devil ray.' A new study shows that these two very different features have the same origin -- a discovery that reflects an important lesson for understanding the diversity of life. Source 3i.
