Why is an elephant pregnant for 2 years?
The mystery of the elephant’s long pregnancy has been unravelled by scientists. A quirk of biology allows the unborn calf to develop in the womb for almost two years, giving it the brain power it needs to survive from birth.
How often can elephants reproduce?
Most female domesticated elephants begin to come into heat starting at about 9 years old or later and enter their ‘heat cycle’ which has a length of about 16 weeks or 4 months. Thus, in a period of one year, the average female elephant will be able to breed and become pregnant only about three times in a year.
How often do elephants have twins?
Unlike other animals, elephants usually only have one baby at a time. However, there are cases where elephants can have twins, but this only happens in one per cent of elephant births. This is only slightly smaller compared to humans, where 1.6 per cent of births are twins.
Which animal has the most painful birth?
Perhaps the most horrifying birth is that of the spotted hyena. Females of this species give birth through a narrow, penis-like, enlarged clitoris.
