There were many studies done on not only bats, but also sheep, chickens, wolves, dogs, elephants and many other animals. Many animals are able to recognize each other through sound, by the calls, grunts, rumbles, squeals and chirps that are used to communicate to each other. Many animals, however, don't rely on sound to recognize each other (bats have to because they don't see very well), but go more for facial recognition like humans do. Scent is very important for wolves, dogs, sheep, goats and cattle because it tells everything about the other animal.
Some animals identify their offspring visually.Others depend on the voice.Some animals lick their babies at birth,marking them with a chemical tag,that they can identify.
Actually, in pretty much the same way us humans do - by a combination of appearance, calls behavior and smell. The exact contribution of each sense varies from species to species.
the offspring of most animals are a mixture of features from both
Animals don't always produce identical offspring. Like cats for an example.
The offspring of different animals are known by different names- for example the oppsring of a Lion is called a cub, that of a cow is called a calf and so on.
Inbreeding!
Animals use their skin to identify food through the sense of touch. The skin is also use for other things like keeping the animals warm.
No, not all animals need to mate to have offspring.
Hybrid animals cannot have offspring.

Offspring
The females do the rearing of the offspring. In fact, some male animals are known for eating their own offspring, like Lions. Males are usually highly aggressive to their offspring.
Animals don't always produce identical offspring. Like cats for an example.
The 'offspring' for animals refers to their young.
Because they are tasty
Offspring
Animals or even humans couldnt produce offspring.
they do the same as animals do today.
Territory, offspring, and mates.
