Happy Father's Day! To help you celebrate in the most adorable way possible, here's a compilation of the animal kingdom's best fathers. Tamarins (small monkeys native to the Amazon forests) carry their babies on their backs, and deliver them to Mom when it's feeding time.
To start off the list, here's what makes the Emperor penguin (above) such a great dad: while mom replenishes and feeds in the ocean after laying the egg, dad spends two months watching over it, holding the egg snug in a cozy pouch between the tops of his feet. To keep the egg safe, he waddles and shuffles gently to move around, waiting for his baby to hatch. Adorable!
Male rheas build a huge nest and then mate with multiple females, who then lay all the eggs in the same nest, sometimes more than 50! The male rhea incubates and raises the young, aggressively protecting his brood, for the next six months.
Male owl monkeys, who form lifelong partnerships (aww) perform most of the legwork in the early stages of child-rearing. Dads carry and groom the babies, while the mother nurses them.
The Namaqua Sandgrouse incubates his chicks and keeps them hydrated in the desert by wetting his own belly feathers, which retain more water than his other feathers, and then letting his chicks drink from his belly.
Male Cygnets carry their babies on their backs and keep them warm and dry for the first few weeks of their lives.
Marmosets are great dads because they not only feed, carry, and groom their babies, but also monitor them during the birthing process, grooming and licking them.

While the female wolf nurses her newborn pups, the male hunts for food and guards the den. When the wolf pups are big enough to play, dad engages in lots of gentle roughhousing to teach them how.
Seahorses are a rare breed because it's the males that give birth. The male fertilizes the eggs and incubates them for up to 45 days until they emerge.
Barking frogs protect his brood for weeks, hanging out nearby and wetting them with his urine if they dry.
The Arowana builds nests for his young and protects his babies by harboring them in his mouth, letting them out to explore and then sucking them back in when predators are near.
The male jacuna makes the nests, incubates the eggs, and cares for the chicks. The male is such a good father that he will often care for eggs fertilized by other males.
The Giant African Bullfrog (big as a football!) protects his tadpoles in their diminishing nursery by digging a canal to help them move to a bigger pond, ensuring their survival.
The Marsupial Frog also guards his eggs, patiently waiting for them to hatch. When the time comes, the marsupial frog sits on top of the eggs, liquifying the egg membranes so the tadpoles can break free. He stores the tadpoles in two pouches on his body in protection.
