Some animal fathers incubate eggs, carry infants, guard nests, or help feed young; seahorse fathers even carry developing eggs in a pouch and give birth. Here are ten notable examples of paternal care, from emperor penguins and frogs to primates and insects. “Best” is an editorial description, not an objective scientific ranking, and care varies among individuals and species.
The examples are compared by the kind of care males provide and whether they act alone or alongside a mate or group. Many of these animals share parenting duties, so a father’s contribution should not be confused with father-only care.

Animal dads at a glance
| Animal | Kind of care | How care is shared |
|---|---|---|
| Emperor penguin | Incubates an egg through the Antarctic winter | Male incubates while female forages; parents share later care |
| Seahorse | Carries embryos in a brood pouch and gives birth | Female deposits eggs; male carries developing young |
| Marmoset | Carries infants | Father and other family members may help |
| Arctic wolf | Guards and helps provision pups | Pack members also participate |
| Owl monkey | Carries and supports infants | Father carries while mother continues nursing |
| Poison-arrow frog | Guards eggs and carries tadpoles to water | Male provides the described egg and tadpole care |
| Stickleback | Protects the nest and returns stray fry | Male nest care; behaviors vary by species and individual |
| Giant water bug | Inspects and tends the egg clutch | Male removes dead or moldy eggs |
| Red fox | Helps feed and protect young | Male contributes alongside family care |
| Emu | Recognized as an example of paternal care | Available source supports only a general description |
1. Emperor penguin: egg incubation through winter
After a female emperor penguin lays an egg, the male balances it on his feet and covers it with a brood pouch while she goes to sea to feed. WWF describes the male fasting for about two months as he incubates the egg through the Antarctic winter. This striking seasonal division of parental labor is one example of fathering, not a universal pattern across animals.
2. Seahorse: carrying young and giving birth
The female seahorse deposits eggs in the male’s brood pouch. He fertilizes and incubates them there, then gives birth to developed young. Seahorse pregnancy is a distinctive form of male care; the pouch is a fish reproductive structure, not a mammalian placenta.

#1 Best Overall
Sources give somewhat different durations for seahorse pregnancy, so it is safer not to assign one exact timeline across species. WWF’s accounts put it at roughly two to four weeks.
3. Marmoset: carrying infants with family help
Marmoset fathers help carry infants, and other family members may share the work. Research on common marmosets describes substantial paternal care but also variation in how strongly individual fathers respond. The father is an important caregiver, but not necessarily the only one.
4. Arctic wolf: guarding and provisioning pups
Arctic wolf fathers can guard the den and help hunt for food for the pups. Wolf care is cooperative: other pack members also participate in raising young. The father’s contribution belongs within that wider family and pack effort.

5. Owl monkey: carrying while the mother nurses
Owl monkey fathers provide substantial infant carrying and support. An account published in 2004 describes the father taking on dorsal support and transportation after an initial period when the mother carries the infant; the mother continues nursing. The timing and extent of care should not be assumed to be identical in every family.

PBS NOVA describes a male Panamanian poison-arrow frog sitting on eggs and keeping them hydrated. Once the eggs hatch, he carries tadpoles on his back to water. “Poison-arrow frog” covers a group of frogs, so this example is best understood as a reported behavior rather than a claim about every species in the group.
7. Stickleback: protecting the nest and fry
Male sticklebacks can protect their nests and, after hatching, collect stray fry in their mouths and return them to the nest, according to PBS NOVA. This describes a behavior pattern, not a rule for every stickleback species or every male.

8. Giant water bug: tending an egg clutch
PBS NOVA describes male giant water bugs inspecting their egg clutches and removing dead or moldy eggs. This invertebrate example adds a different kind of paternal care to the list: tending the condition of eggs rather than carrying or feeding young.
9. Red fox: helping feed and protect young
Red fox fathers help provision and protect their young, according to PBS NOVA and WWF UK. These accounts support a careful description of a paternal contribution; they do not establish that every father performs every task or that males are the family’s sole providers.
10. Emu: a modest example of paternal care
Taipei Zoo identifies emus as an example of devoted paternal care. The available account does not provide detailed behaviors, so this entry is intentionally brief rather than assigning the male a specific task that the source does not establish.

What animal fathers have in common
These examples show that paternal care can happen at different stages of a young animal’s life and take very different forms. Some males incubate eggs or tend a clutch; others carry infants, guard a den, or help provide food. Care may be provided by a father alone for a particular task or shared with a mate and other group members.
There is no source-supported common score that ranks these animals objectively. The useful comparison is what males do, when they do it, and whether they share care with others.

Which animals are the most devoted dads?
There is no objective ranking of animal fathers. Emperor penguins, seahorses, marmosets, wolves, and several other examples here show notable forms of male care, but the kind and extent of care differ among species and individuals.

Which animal father carries developing young in a pouch?
The male seahorse carries developing eggs in a brood pouch, where he fertilizes and incubates them before giving birth to developed young.
Do animal fathers raise their young alone?
Not always. Wolf pack members and marmoset family members can contribute to care, and owl monkey mothers continue nursing while fathers carry infants. Paternal care may be one part of a wider family effort.
What do poison-arrow frog fathers do?
PBS NOVA describes a male Panamanian poison-arrow frog guarding eggs and keeping them hydrated, then carrying hatched tadpoles on his back to water.
Does paternal care mean animals feel love like humans do?
These behaviors show observable investment in offspring, but they do not by themselves establish human-like emotions or intentions. It is more precise to describe what animals do—such as incubate, carry, guard, or feed their young.
