Happy Father's Day! In honor of all the wonderful dad's out there, we're celebrating some of the best fathers of the animal kingdom.

Emperor Penguins are one of the best dads in the animal kingdom because after the females lay their egg, the males incubate the egg for up to four months! During this time the males do not eat and must endure sub-zero temperatures. All this dedication is why we think Emperor Penguins have earned the title of Best Animal Dad!
