"Ranitomeya imitator" - truly a master of bamboozle. The picture above shows the frog's various color morphs and how they each imitate other species of the "Ranitomeya" genus. Since their discovery in the 1980s, they've been one of the most heavily studied species of poison frogs. Quite unusually for frogs, it was found that they are both monogamous, and that they care for their tadpoles. (That is when they don't elope with some other frog under an assumed identity)
Oh no. I've already committed to the relationship!
