Some sharks have surprised scientists by producing parthenogenetic offspring in captivity, when no males were present
These giant lizards can also produce parthenogenetic offspring in captivity or in the wild when males are scarce
These domestic birds usually need a rooster or a tom to fertilize their eggs, but sometimes they can produce parthenogenetic offspring
These sea creatures can regenerate new bodies from severed limbs, creating clones of themselves
Some species of these lizards are entirely female and can produce clones of themselves
These plant-sucking insects can reproduce rapidly by producing clones of themselves during summers
These female fishes use sperm from other fish species to trigger their eggs to develop, but the sperm does not contribute any genetic material
These freshwater crustaceans are all female and can produce identical copies of themselves
Some female bees and wasps can lay unfertilized eggs that develop into males, while fertilized eggs become females
These leaf-like bugs can switch between sexual and asexual reproduction, depending on the availability of males
