Aphids are the classic example of animals born pregnant, as they reproduce via parthenogenesis, allowing a daughter developing inside her mother to already have her own eggs ready to hatch, creating "telescoping generations". Other examples involve paedogenesis (larval reproduction) in axolotls, where young reproduce at larval stages, and some aquatic salamanders, but aphids are the most direct example of being "born pregnant".

Can human sperm get any animal pregnant?

What animal gets pregnant by itself?

Fish, snakes, lizards, and even birds have all been observed to be able to reproduce without fertilization—a phenomenon known as parthenogenesis. Asexual reproduction, or the ability of a parent to clone itself to produce offspring, is common for many plants and invertebrates—for example, sea stars.

Why do female snakes eat male snakes after mating?

Females exercise mate choice, rejecting unwanted and unfit males by cannibalizing them. Mate choice often correlates size with fitness level; smaller males tend to display a low level of fitness; smaller males are therefore eaten more often because of their undesirable traits.

How long is a salamander pregnant?

Between 650 and 1,000 metres, it typically takes two years but between 1,400 and 1,700 metres, gestation can take up to three years. The young salamanders find nourishment from various sources throughout their development. First, they eat their own yolk, then they feed from the yolk of other eggs.
