When searching for light and a mate in the deep, dark sea, male dragonfish grow larger eyes, scientists discover

A small but ferocious predator, the male dragonfish will apparently do anything for love. Or at least to find a mate. A study by researchers at Boston College found that the eyes of the male dragonfish grow larger for mate-seeking purposes, making the dragonfish an anomaly in vertebrate evolution. The team report their findings in the journal Biology Letters.
