Being a father in the animal kingdom isn't easy. With the species' survival often falling under his daily chore list, some animal fathers will go to great lengths to ensure their young and even mates and entire tribes are well cared for. Here are five animal dads and their unique parenting styles that deserve a special day in their honor.
The task of caring for newborns falls to the male marmoset. They lick and groom them from birth while the mothers recover from labor, and they continue to stay by their side. Males never stray from their baby's mom despite the common myth that a male's animal instinct is only to spread his genes.
Marmoset fathers are also hands-on during birth, going as far as to clean up the afterbirth and bite off the umbilical cord. In rearing, he becomes responsible for feeding his young and carrying them on his back until they're strong enough to venture independently.
Barbary Macaques show their worth
Not to be outdone by a fellow primate, male Barbary macaques predicate their entire social status upon their young. Dads carry infants on their backs, showing them off as a way to impress each other and build social networks. These monkeys live in troops about 30 members, and their culture revolves around the babies born each spring.
During baby season, males will even pick up offspring that aren't their own to parade around, showing that they're sought-after providers for their entire society.
Seahorses do it all
Seahorse dads are the ultimate catch in oceanic #couplegoals. They're the ones to get pregnant and brood eggs in their pouch until birth. The process goes like this: the female transfers her eggs to the male's abdominal pouch, made of modified skin. The male releases sperm to fertilize the eggs as they enter and then incubates them for 24 days until they are born. When the tiny eggs hatch, he keeps them in his pouch until they're accustomed to the sea's salinity. The icing on the cake: male seahorses are monogamous, mating for life.
Sand grouses go the extra mile
Young sand grouses - ground-dwelling birds that live in Namibia's arid deserts - don't have access to life's most essential resource: water. So sand grouse fathers come to the rescue by undertaking a grueling commute of almost 125 miles each day to make sure their family has water.
Once at a pool, male sand grouses rock back and forth in it to soak their belly feathers, which hold water in hairlike coils. This isn't any luxury dip in a pool: filling up can take 15 minutes, exposing them to predators like swooping falcons. At the end of a long day of travel, the dads are able to provide their young with a few precious tablespoons of water that the chicks suck from their father's belly feathers.
Penguins have the utmost patience
Penguin dads take over egg-sitting duties for weeks while mom heads to sea to hunt. Males fast while she's gone, but if the chick hatches before her return, dad will regurgitate a curd-like substance to feed the newborn.
Males are so important to the brooding process that females purposely seek pudgy partners who can last longer without food. Females can tell how fat a male penguin is by listening to his hoarse mating cries, which sound like the cross between a donkey and a stalled car—the buffer the male, the steadier his call.
