Most animal dads aren’t too involved with their offspring (human dads, excepted of course). But two species of frogs called microhylids are devoted dads, and in fact, carry their their brood of up to 25 froglets piggyback style through the rain forest of Papua New Guinea. The frogs were discovered by evolutionary biologist David Bickford.
While most frogs start their lives as tadpoles, these frogs bypass that stage and go straight from larvae to miniature versions of adults while still inside the egg. This allows them to reproduce in areas without bodies of water nearby.
After the mother frog lays the eggs, she hops off while Dad watches over the clutch, warding off predators, and keeping the eggs moist for about a month.
After the froglets hatch from the eggs, they hop on Dad’s back. He carries them by night through the leaf litter in the rain forest. The froglets have a free ride until they grow up a bit and can live independently (hmmm…sounds familiar).
