Do all Female animals go undergo Mensturation
Dear student
All female animals do not menstruate. Only mammals have mentrual cycle. Birds, Reptiles, Fish are the non-mammals so they do not have a menstrual cycle.
Most of mammals have a covert menstruation. This means the endometrial lining is so thin; it gets completely absorbed by the body if the egg isn’t fertilised.
But on the other hand, Humans, primates and some other mammals have such a thick endometrial lining that part of it is being shed through the vagina.
