Reproduction is the fundamental feature to all living life. Each organism on earth exists because of reproduction, rather than its through asexual or sexual reproduction. There are two main types of reproduction, sexual and asexual. There are many plants, animals, insects, bacteria, fungi that are asexual and reproduce with no mate. Asexual reproduction is when the individual produces the offspring and the offspring is more identical to itself. The offsprings are formed by mitosis.
4 Animals That Are Asexual
- Whiptail Lizard
Whiptails lizards are crossbreeds between which could be the reason why they have several chromosomes. They need not chromosomes to reproduce healthy eggs and offsprings. It is said that these whiptail lizards are freaks because before laying their eggs they mount other lizards. Pseudo-sexual behavior is among unisexual lizards.
2. Komodo Dragon
The female Komodo Dragon can lay eggs that turn into healthy offspring without having sex with a male Komodo Dragon counterpart. This was just recently discovered by scientists in 2006 when they noticed a female Komodo Dragon in a zoo named Flora laid healthy eggs without ever been exposed to a male Komodo Dragon. Female Komodo Dragons have two sex chromosomes, a Z and W, unlike the male dragon who has ZZ chromosomes.
3. Marmorkrebs Crayfish
Back in 2003, there was an experiment by a biologist reported by TIME Magazine on a female marmorkrebs crayfish. The biologist stated the Female Crayfish was in an aquarium by herself and ended up laying multiple eggs that developed into her offsprings. The scientist looked heavily for sperm or male gonads that could have been hiding in her cavity’s so she could fertilize the eggs, but they found nothing.
4. Hammer Head Sharks
In 2007 researchers found a female shovel-head that had not been exposed to any male hammerheads had laid eggs with a full set of chromosomes her female genetics had doubled that. This is a process called automatic parthenogenesis.
