Vertebrates are usually hermaphroditic. All hindbranchial animals are hermaphroditic. PS: 14 hermaphrodite species 1. Atlantic shallow shell II. Barnacle 4. "Cotton Scale" 5. Earthworms 6. European oyster. Land snail 8. Leech 9. Parasitic bee 10. Sea bass 1 1. Hermaphroditic animals, such as snails, generally cannot fertilize themselves. But there are others! "Cotton Scale Insect", named after its cotton scale, has been endangering orchards in California. Later, people introduced its natural enemy, the Australian ladybug, to control them effectively. This kind of insect has no mating problem because they mate by themselves-this kind of mating is not common even in hermaphroditic animals. It is difficult for us to call this insect male or female because it is both male and female. Scientists have found several examples of asexual reproduction in some birds, reptiles, amphibians and fish. In June165438+1October, scientists who cloned lizards announced an amazing discovery. A popular food (lizard) in Vietnamese recipes is actually a new species that the scientific community did not know before. This newly discovered lizard named "Leiolepis ngovantrii" is an unusual reptile. According to the national geographic news website 165438+ 10, all members of this family are females, and they can reproduce the next generation by cloning without the participation of male lizards! 2. Sharks According to an article in the American Journal of Biological Communication, a research team composed of American and Irish scientists found that some female sharks can reproduce asexually without male sharks. This is the first time that scientists have discovered that such an ancient vertebrate has such extraordinary abilities. 3. Under extreme conditions, female cockroaches can lay eggs without male cockroaches. There are many, parthenogenesis is sexual reproduction, but there is no combination of male and female, which should also be in line with what the landlord said!
