Animals: these caring fathers who raise their little ones

The ostrich incubates at night

Depending on the number of partners available, the ostrich can mate with several females. It is then he who decides the location of the nest. Once the eggs are laid, Madame incubates during the day and Monsieur at night. Once born, the little ones will live with their parents for about a year, and the father will actively participate in their education and protection.

It sometimes happens that babies are chased away by their parents when they are only a few weeks old when they want to mate a second time. The small orphaned ostriches are so often adopted by “single” males who have not been able to reproduce.

The seahorse fertilizes the eggs

He is the ultimate super dad. During the mating season, the seahorse introduces its fallopian tube, a conduit through which the eggs pass, into the male’s sac. And his role ends there. The male will fertilize the eggs and then carry them for a few days to two months, depending on the species. It will generate oxygen in its ventral cavity and transfer a nourishing fluid and saline to the eggs via a network of capillaries, to ensure their growth. When the time comes, the father will have labor pains and expel his hundreds of babies one by one. A very trying birth that will last for hours. But when they are born, the little seahorses will be left to fend for themselves. The father, he’s going to have to recover physically … before he does it again!

The cat keeps its eggs in its mouth

In some fish, the males practice mouthwash. After spawning, the fathers keep their eggs in their mouths to protect them from predators. Oral incubation continues even after hatching, as long as the pups have their yolk sac, for a total duration of 8 to 11 weeks. But farrowing hens may even decide to continue feeding their young even after this stage, which increases the baby fish’s chances of survival. All this time they can not feed themselves. This technique is mainly used by catfish Ariopsis felis, a slender species 28 to 70 cm long.

The owl monkey takes care of the upbringing of the little ones

Also called “douroucouli”, the owl is one of the animals that stays in a pair all their lives. Extremely loyal, this primate is also a very good parent. The males are thus extremely invested in the training of their young, especially by carrying them on their backs or playing with them. They only return the babies to their mothers for feeding. So when the little ones get bigger, the fathers make sure to feed them. A study has shown that there is no trace of the non-couple’s paternity. This primate lives at night and feeds mainly on insects, and fruits, small animals and eggs complete the menu.

Jacana incubates the eggs

The Jacanas are small waterfowl with long legs, which means that they do not sink into the submerged vegetation when they move. In this species, the roles are reversed: it is the females, more massive, who fight among themselves to win the right to reproduce, generally with more partners. It is then these ladies who make sure to ensure the safety of their families. Conversely, the males are responsible for caring for the young. These gentlemen incubate the eggs and then make sure to raise and feed their offspring.

Rhea, a very invested father

A cousin of the ostrich, the rhea is a large bird from South America. Like the ostrich, it can not fly, handicapped by its 140 cm height and its 25 kg. The male mates with several females, and these all come to lay eggs in his nest. It is the lord who has to take care of the hatching, which generally includes 10 to 16 eggs. The father will then take care of the young people and provide them with food, education and protection.

The male emperor penguin watches over the eggs

The emperor penguin has adapted perfectly to where it lives. It is thus able to reproduce under extreme conditions, at -60 ° C, in the Australian winter. Once her individual eggs have been laid, the female transfers it to her companion’s feet and fishes for long weeks. It is therefore up to the father to take care of the egg, to protect it from the cold and take care not to crack it. For this, the fathers keep the egg on their feet, warm under the stomach, at a temperature of 31 ° C. To maintain this heat during storms, for example, the males group themselves together and start a “turtle”. This is a technique where individuals stick to each other and move forward constantly. Animals outside the grouping move gradually inside and vice versa. During all this time, the males do not eat and lose a lot of weight, sometimes up to 45% of their original mass.

In the giant water belly, the male carries the eggs on his back.

As the name suggests, the giant water belly is a large insect that can grow up to 7 cm. It is found mainly in stagnant water. Also called “lethocerus”, there are several species. The females lay up to 150 eggs on aquatic plants. But in some species, these females prefer to lay their eggs … on the backs of males. These are therefore responsible for ensuring the protection of their offspring until hatching. A great way to ensure their survival against predators.
