Reproduction

Galápagos Tortoises, also referred to as giant tortoises, reach sexual maturity around 20-25 years of age. These remarkable creatures display specific breeding behavior during the hot season from January to May. Mating can be a lengthy process, often extending to several hours. The male Galápagos Tortoise contributes to the courtship ritual by emitting loud roaring noises that echo throughout their habitat.

Following successful mating, the female Galápagos Tortoise embarks on a migration to a designated nesting area. Once arrived, she carefully excavates a hole in the ground using her strong limbs and buries her precious clutch of eggs. The number of eggs laid by the female Tortoise can range from 2 to 16, representing new generations of these incredible creatures.

The eggs are then left to incubate under the nurturing warmth of the sun. The incubation period typically lasts approximately 130 days, during which crucial growth and development occur within the fragile shells. It is essential to note that the temperature of the nest determines the sex of the hatching tortoises, with warmer conditions favoring the emergence of female offspring. This delicate balance adds to the intricate and fascinating life cycle of the Galápagos Tortoise.
