The number of eggs a sea turtle lays depends on its species, but the turtles lay an average of 110 eggs in a nest. Flatback turtles lay the least amount with about 50 eggs in a nest. Hawksbill turtles lay the most eggs with more than 200 in one nest.
The group of eggs in a sea turtle's nest is called a clutch. Sea turtles lay between two and eight clutches per season. The eggs resemble ping-pong balls in size and shape, and they have a soft shell. They are usually round but can be misshaped from elongation or from joined calcium strands.
