Mating and Reproduction

The males compete with each other and the strongest one wins and gets to mate with the female. The courtship is known to last for a month and the breeding season is during April and May. After 6 months of gestation period while the eggs hatch inside the mother’s body the female gives birth to baby snakes ranging from 4 to 80 in numbers.
Young anacondas sizing 23 inches are self-dependent right from their birth and they attain sexual maturity at the age of 3-4 years.
