Ovoviviparous animalsPosted on May 18, 2018 - Last modified: September 8, 2018
Ovoviviparous animals are a mix between oviparous animals (That lay eggs) and viviparous animals (Which develop inside the female's womb). Ovoviviparous animals develop and grow inside an egg that the mother keeps inside her body and cares for it until it hatches.
Characteristics of ovoviviparous animals
Within ovoviviparous animals we have many species of fish, invertebrates and reptiles. This type of reproduction originated thanks to an evolution adapted to the climate, predators, geographical location, etc.
Reproduction and adaptation
Fertilization is internal, like the development of the embryo, but unlike viviparous animals, it is done inside an egg, where it is protected by the female. Inside the egg they feed on the nutrients that the egg itself provides.
There are animals where the egg breaks inside the mother and they are born alive and adapted to the world around them. We also have animals where the female expels the egg and they wait to hatch, once they hatch the female takes care of them until they are self-sufficient.
