Reproduction is something characteristic of living beings. In the vast majority of animals it occurs sexually, that is, with a male and a female. However, some species are able to do this asexually, without the need for two parents. Discover now some animal species that reproduce alone.

A curiosity is that most lizards reproduce asexually, for example, the species Cmenidiphorus uniparens is composed only of females that manage to reproduce without males. In this sense, the animals are genetically identical to the mother, as if they were clones.
See the list with other animals that, although they may have partners of different sex, do not depend exclusively on mating to maintain the existence of the species. In addition, despite being a phenomenon observed more frequently in invertebrate animals, vertebrates are also capable of performing. Check out!
Some species of snakes are able to reproduce through parthenogenesis (a form of reproduction in which only female gametes are needed). The phenomenon has already occurred with different snakes raised in captivity, especially with some species of vipers.
Did you know that today there are around 20,000 species of bees around the world? However, only one of them can reproduce without the presence of a male.
The Cape honey bee originates from South Africa and can carry out a process called thelytoky. That is, a form of parthenogenesis in which worker bees lay diploid eggs, that is, with two chromosomes, and give rise to females.
Parthenogenesis in sawfish was first identified in 2015 through DNA testing. Being, so far, something practically unheard of in vertebrate animals free in nature, given that the other On occasions when this type of reproduction has been seen in vertebrate animals such as birds and sharks, they have been in captivity.
Although there are enough males and females to perpetuate the species, female stick insects realized that the sexual act was suffered and, therefore, they even started to produce an “anti-aphrodisiac” that alters their pheromones, in this way, they are not noticed by possible partners.
As they generate clones of themselves through parthenogenesis, a concern would be in relation to the population of males, however, scientists claim that the male animals of this species are not threatened.
