Non-human fatherhood
For some animals, it is the father who take care of the young.
- Some male frogs carry unhatched eggs on its back, such as Gastrotheca, Hemiphractus, Flectonotus, and Fritziana. Darwin frog (Rhinoderma darwini) fathers carry eggs in the vocal pouch.
- The female seahorse (hippocampus) deposits eggs into the pouch on the male's abdomen. The male releases sperm into the pouch, fertilizing the eggs. The embryos develop within the male's pouch, nourished by their individual yolk sacs.
- Unlike most birds, it is the Emperor Penguin fathers who sit on top of the nests.
