How do animals get pregnant?
During copulation, the male inseminates the female. The spermatozoon fertilizes an ovum or various ova in the uterus or fallopian tubes, and this results in one or multiple zygotes. Sometimes, a zygote can be created by humans outside of the animal’s body in the artificial process of in-vitro fertilization.
Can female seahorses get pregnant?
But in seahorses, the sperm-producers are also the ones that get pregnant. The female transfers her eggs to the male’s abdominal pouch, made of modified skin. The male releases sperm to fertilise the eggs as they enter, before incubating them for 24 days until they are born.
Do insects get pregnant?
Most insects reproduce oviparously, i.e. by laying eggs. The eggs are produced by the female in a pair of ovaries.

The sperm is stored within the female in one or more spermathecae.
Can aphids be born pregnant?

Are aphids poisonous to humans?
A sticky situation Although woolly aphids aren’t dangerous or poisonous to humans, they’re considered a notable nuisance; the irritant itself comes from what woolly aphids produce – honeydew.
Do ants attract aphids?
Did You Know? Several species of ants have a special symbiotic relationship with aphids- they farm them! Aphids feed primarily on the sap from plants and secrete a liquid called honeydew. This secretion is very sugar-rich, and quite favoured by ants as a food source.
Why aphids are mostly found in the daytime?
When daytime high temperatures are between 90 and 95oF reproduction decreases and when daytime high temperatures are above 95oF death occurs. If high populations are reached during the summer, winged females are again produced that migrate to other soybean fields.
Do ants and aphids have a mutualistic relationship?
Ants and aphids have a symbiotic relationship. Both species of the insects benefit from being together on the stems of those wildflowers. The ants provide protection from any predators that might go after the aphids. The aphids, in return, provide food for the ants.
