Ovoviviparous

Fish that fertilizes and makes her eggs incubate in the body of the female.

The term OvoviviPare refers to a mode of reproduction in certain animals, which implies the gestation of eggs inside the mother's body, but without the eggs being laid. Instead, the eggs are retained inside the maternal organization until they are ready to hatch and the little ones are born.

In ovoviviparous animals, the fertilization of eggs can occur inside or outside the mother's body. In the first case, we are talking about true ovoviviparity, while in the second case, we speak of false oviviviparity.

In the field of aquarophilia, there are several species of fish which are ovoviviparous. This means that the females carry the eggs inside their bodies until they are ready to hatch and that the fry is born. Dolds can be fed by food eggs produced by the mother, or by specialized glands that produce food for fry.

There are several advantages in this reproduction mode. First of all, the eggs are protected inside the mother's body, which shelters them from unfavorable weather predators and weather conditions. In addition, the mother can control the temperature and humidity of the environment where eggs and fry develop, which can improve their survival rate. Finally, fry can be more effective and better protected by the mother until they are able to fend for themselves.

However, there are some drawbacks in this reproduction mode. First of all, the mother must devote a lot of energy and time to the gestation and food of the fry, which can make her vulnerable to predation. In addition, fry can be exposed to infections or diseases transmitted by the mother. Finally, ovovivipar species often have relatively low reproduction rates, because they only lay a limited number of eggs at a time.

In summary, the term OvoviviPare refers to a mode of reproduction in certain animals, which implies gestation of the eggs inside the mother's body until they are ready to hatch and the little ones are born. This helps protect eggs and fry against unfavorable predators and weather conditions, and control their development environment. However, this can also expose fry to infections and diseases transmitted by the mother, and cause relatively low reproduction rates.
