Nipples are the external opening of the mammary glands.
Yes they do
Boy guinea pigs don't have nipples.
Yes they do my two girls are both 23weeks and they have nipples :)
yes, females yes, females
No, as both boars and sows have nipples. The only way to determine gender is by the reproductive organs themselves.
after being pregnant for a couple of weeks
A pig has as many nipples as the litter they will have. If they have 10 nipples they will have 10 pigilets per litter Not always the norm. They can have 6-12 nips. and maybe 1-6 babies, as in the case with Micro pigs. A Micro pig breeder will NOT usually breed a Micro with less than 10 nipples. This is just a standard. Some breeders will not breed sows with narrow hips,either.
The external auditory aperture is present in fetal pigs. This organ is the eventual opening for the auditory lobes in adult pigs.
Both male and female guinea pigs have two nipples located on their lower abdomen. These nipples are more prominent in female guinea pigs, as they are used for nursing their young.
No boys don't, only females do cause female Guinea Pigs feed milk to their young ***Answer 2*** Like human males, yes Guinea Pig males also have nipples. But the nipples are totally useless. I know this because I've had male and female guineas. Its the same with pigs, dogs, goats. People often think my piglet is a girl, but he has his 'parts' Same with my cute goat kid. Dont think male horses have nipples though
a female guinea pig has nipples and milk glands but it is not called boobs.
Well honey, pigs typically have 6 to 10 teats, but not all of them develop into functional nipples. So, to answer your question, pigs usually have around 6 to 10 nipples, but not all of them may be fully functional. Hope that clears things up for ya!
