The incubation period of turtle eggs varies significantly depending on factors like species, temperature, and humidity. Generally, the eggs of green turtles take around 50-70 days to hatch, loggerhead turtles require 55-80 days, and diamondback terrapins incubate for about 55-90 days. The incubation period can play a crucial role in the hatching success of the eggs, as temperature fluctuations and external factors can impact embryo development and survival.
