After mating, some of the males of these organisms can be seen staying with the female species for days to ensure she doesn’t mate with another male. These animals exhibit mating behavior during the mating season where they fight with each other aggressively. The Komodo dragon has been discovered recently as one of the asexual animals. Genetic analysis and testing were carried out on the offspring, the mother shark, and the suspected father shark but there was no trace of paternal genetic material as the offspring only inherited DNA from their mother. In 2017, this shark gave birth to 3 baby sharks even after being without a mate for 5 years. Even though the wild-caught shark hadn’t been exposed to a male in at least 3 years, it still reproduced and gave birth to offspring and studies showed no evidence of any genetic contribution from paternal sources.Īlso, the first evidence of any species of sharks switching from sexual reproduction to parthenogenesis was exhibited in a zebra shark named Leonie in Australia. A captive hammerhead shark in 2001 was the first evidence recorder of parthenogenesis in cartilaginous fishes. An asexual reproduction type known as parthenogenesis whereby unfertilized eggs develop into an embryo has been observed in female animals that are separated from the males for long periods due to captivity. One of the animals that reproduce asexually is the shark. Let’s look at some of the animals that reproduce asexually. In some cases, some of them combine or alternate between reproducing sexually or asexually due to some circumstances. In the animal kingdom, there are various animals that reproduce asexually. Thus all members of the population are prone to the same predators and diseases.Įven though asexual reproduction is typically common among unicellular organisms and plants, there are several cases of asexual reproduction in animals. This kind of reproduction in animals can increase population rapidly the downside to reproducing asexually is that the population of the organism is only best adapted for a specific habitat.
