Birds:
* Emperor penguins: The male incubates the egg for 64 days while the female returns to the sea to feed.
* Seahorses: The male carries the eggs in a pouch on his belly until they hatch.
* Ostriches: The male incubates the eggs and cares for the chicks, while the female may leave to find another mate.
* Albatrosses: Both parents take turns incubating the egg and raising the chick.
Mammals:
* Mountain lions: The male may help protect the young but generally doesn't directly raise them.
* Wolves: Both parents raise the pups.
* Sea otters: The male may help defend the pups.
Other:
* Stick insects: The male may guard the eggs and help the nymphs hatch.
It's important to note that in many species, both parents share the responsibility of raising their young. However, in the cases listed above, the male plays a particularly significant role.
