The Life Cycle of a Sea Turtle — Reading Comprehension

Sea turtles have an amazing life cycle that starts on land but mostly takes place in the ocean. The cycle begins when a female sea turtle comes ashore to lay her eggs. She uses her flippers to dig a deep hole in the sand, called a nest. Then, she lays about 100 soft-shelled eggs, each about the size of a ping-pong ball. After covering the nest with sand, she returns to the sea.

The eggs stay buried in the warm sand for about two months. The temperature of the sand determines whether the baby turtles will be male or female. Warmer temperatures produce more females, while cooler temperatures result in more males.

When the baby turtles are ready to hatch, they break out of their eggs using a special tooth called an egg tooth. It takes them several days to dig their way out of the nest. Once they reach the surface, they immediately head towards the brightest horizon, which is usually the ocean reflecting moonlight or starlight.

This journey from nest to sea is very dangerous for the baby turtles, also called hatchlings. Many are eaten by birds, crabs, or other predators. Those that make it to the water face new challenges from fish and other sea creatures.

The young turtles that survive spend their first few years in the open ocean. As they grow, they move to coastal areas where they can find plenty of food. Depending on the species, sea turtles take anywhere from 10 to 50 years to become adults.

Adult sea turtles spend most of their lives in the ocean, coming to the surface only to breathe and bask in the sun. When it's time to lay eggs, female turtles return to the beach – often the very same beach where they were born. This amazing journey completes the cycle, and it starts all over again.
