The reproduction methods of animals can be mainly divided into the following ten types:
1. [Rose] [Rose] parthenogenesis: refers to the fact that some animals can replicate themselves and do not need a mate, such as some worms and jellyfish.
2. [scattering flowers] [scattering flowers] oviparous: Animals reproduce by laying eggs, such as birds, reptiles, and most fish.
3. [Breeze] [Breeze] Viviparous: Animals reproduce by means of pregnancy, and the fetus develops in the mother and is born directly, such as mammals.
4. [Rabbit New Year] [Rabbit New Year] Ovoviparous: Animals lay eggs first, but the eggs hatch in the mother's body, and the hatched larvae continue to develop in the mother's body until birth, such as some snakes and sharks.
5. Extrauterine pregnancy oviparous: animals lay eggs outside the female when they lay eggs, but the eggs hatch outside the body, such as most arthropods and lizards.
6. [Aimer] [Aimer] Ectopic pregnancy viviparous: Animals leave fetuses outside the body to hatch when they are pregnant, such as moles and kangaroos.
7. [Rose] [Rose] Asexual reproduction: Animals reproduce asexually in different ways, such as hydras, fireflies, etc.
8. [Small applause] [Small applause] Baby reproduction: Female animals do not give birth, but give their eggs to other female animals to hatch and raise babies, such as some birds and reptiles.
9. [laughing cry] [laughing crying] surrogacy: female animals put their own eggs into the womb of other female animals for hatching, such as certain insects and lizards.
10. [Like] [Like] Combined reproduction: Two individuals fuse with each other to form new individuals, such as coelenterates and protists.
