Humans and chimpanzees are the only animals that have "periods" or menstrual cycles. Other animals of the animal kingdom undergo Estrus, or heat periods (spikes in Estrogen output) during their Estrous cycle.
Only if they are girls! But yes they do have periods. Otherwise they could not have babies..... No matter what I'm pretty sure that girl dogs do have periods. So yes animals do have periods!
Not all animals, but most mammals do, hence why people have periods (people=mammals)
Not necessarily. Gestation periods can vary greatly among different species regardless of their size. Small animals like mice can have shorter gestation periods compared to larger animals like elephants. The length of gestation is more closely tied to the specific reproductive biology and development of each species.
I don't think so but maybe it is. But out of prediction I can say that animals that live in water have shorter gestation periods than animals on land because it takes a baby 9 months to get out of the mother's womb. Just my guess.
Yes, this is called "in heat." I don't belive it's as messy as a human.
Camels are just one of the many animals that live in the desert. They can last long periods of time without drinking water.
In terms of animals, pigs, rats and dogs, which were all used for food. It happens that these animals can be kept for long periods onboard boats.
An anoestrus is a spell of sexual respite for certain female animals inbetween breeding periods.
That was the age of the reptiles the "Dinosaurs".
Humans don't get pregnant when they have a period. That's only for animals. Human females mostly get pregnant mid-way between their periods.
The Intertidal Zone
mainly in the Spring time but there are some animals that can be born in other periods of the year
