Do sea turtles reproduce sexually or asexually?
Turtles mate, in male, female pairs. Much like a dog or other four legged animal, the male mounts the female and fertilizes her eggs. Where things change is that the female then, typically, will find an unclaimed area, dig a hole in the sand, deposit the eggs into the hole, and then, at least partially, cover them with sand for the remainder of their gestational period. When the baby turtles hatch, they make their way instinctively to the water, in hopes of avoiding most predators. "Turtle runs", as they are commonly known, are at their height when it is the darkest, as an added security measure. There are some types of turles that live exclusively in the water, or who lay their eggs in the water. For them, the eggs are simply laid in an area where they are less likely to stand out, not necessarily buried. When the babies emerge, they will head to the surface for air, since they need oxygen. *The same applies to tortoises, who are all rounded shell turtles.
