8) Leatherback Sea Turtles Reach Sexual Maturity at a Much Slower Rate

The leatherback sea turtle reaches sexual maturity between 7 and 13 years, a much slower rate than most other species of turtle.

This is due to their large size, which reduces the number of potential mates in the population.

The leatherback sea turtle has a low reproductive rate due to their long lifespan and low number of eggs produced per year.

Leatherback sea turtles lay about 8 to 12 times during one entire nesting season, between the months of April and November, with an interval of 9 to 10 days from one another.

They lay a group of about 100 eggs on average every interval, and they only lay eggs every two to three years.
