Amazing Animal Dads

Meet four fathers from the animal kingdom that raise their young in wild ways

When the babies are fully developed, the seahorse dad releases them from the brood pouch on his stomach.

Every third Sunday in June, we celebrate Father’s Day. It’s a day for human dads, but animal dads deserve their due too!

One extreme animal dad is the seahorse. It’s the male, not the female, that becomes pregnant and gives birth. The process starts with a mating dance, where the pair swims from the ocean floor toward the surface. The dance ends when the female deposits her eggs into the male’s brood pouch. This is a pocket of skin on the male’s belly. There, the eggs are fertilized and develop. It takes from 9 to 45 days for the eggs to hatch, depending on the species and the water temperature.

When it’s time to give birth, the male seahorse spews baby seahorses into the water. But that’s where a dad seahorse’s duties end. “In fact, if the babies hang around for too long, the dad will eat them!” says Camilla Whittington, a biologist at the University of Sydney in Australia.

Emperor Penguins

Every year, these birds go on an epic trek across Antarctica. Emperor penguins leave the coast and walk about 50 miles to their inland breeding grounds in March. By June, the mother penguin lays a single egg, carefully transfers it to the father penguin, and then returns to the sea to feed. Over the next 65 days, the father penguin keeps the egg warm in a pouch of skin above his feet until it hatches. When the mother penguin returns, it’s Dad’s turn to get food!

Emperor penguins go on an epic trek across Antarctica every year. They leave the coast in March and walk 50 miles inland to their breeding grounds. By June, the mother penguin lays just one egg. She carefully transfers it to the father penguin. Then she returns to the sea to feed. Over the next 65 days, the father penguin keeps the egg warm. He has a special pouch of skin above his feet. The egg stays there until it hatches. When the mother penguin returns, Dad goes to get food!

A male emperor penguin weighs 88 pounds at the start of the breeding season. His body weight decreases by 45% while incubating the egg. How much does he weigh when the egg hatches?

Cotton-Top Tamarins

This monkey species lives in South America. The mother typically has twins or triplets, so she needs help! For the first two weeks of the babies’ lives, their father carries the young on his back, bringing them to mom to feed them. Older siblings will also help care for their new siblings.

Cotton-top tamarin dads can lose 10% of their body weight during the two-week period when they are lugging around their newborns. A tamarin dad weighs 1.4 pounds when his babies are born. How much does he weigh two weeks later?

Darwin’s Frog

Living in the streams and rivers of Chile and Argentina, these frogs burp up their babies! First the father slurps the fertilized eggs into his mouth. He stores them in a pouch called the vocal sac. There the frogs grow from tadpoles into baby frogs. After about two months, the dad spits them out of his mouth fully developed!

The Darwin’s frog is an endangered species. Researchers in Chile found 146 Darwin’s frogs in 1998. When they returned in 2011, they found 98.6% fewer frogs. How many did they find in 2011? Round your answer to the nearest whole number.
