It’s an amazing fact that besides the technological
advancements humans have not yet been able to observe the birth of the
dolphins in the wild. For now whatever information has been gained is
based on the dolphins in captivity. So today we are going to share this
miracle birthing process of the dolphins with you. The period of sexual
maturity differs in both males and females and also the geographical
location play an important role in sexual development. The maturity age
for male dolphin is 10 to 15 years, whereas for females sexual maturity
begins at an early age i.e. at 5 to 13 years. Another interesting fact
is that in most cases the sexual maturity determinant is the body size
and not the age. When females gain 85 to 95% of adult body size they
reach sexual maturity. Female do not have a constant ovulation cycle and
they are believed to ovulate spontaneously for one to six times in a
year. Usually the presence of a male dolphin stimulates ovulation.
Unlike other monogamous mammals, dolphins breed with several partners
during the breeding season.
