- Green sea turtles are solitary for most of their lives, but congregate during mating season. Males and females look identical until they reach sexual maturity (around 25-50yrs old). Once mature, males have a longer tail, a longer carapace, and mating claws that develop on the edge of their front flippers. Females will return to the same beach each year to lay their eggs, sometimes travelling up to 1000km to reach their goal. Because of the physical demand of travelling to the distant beaches, female sea turtles will not reproduce every year. Instead they will breed only when their fat reserves are large enough to accommodate travel, sometimes between 2-4yrs apart. They will lay around 100 eggs.
- When the young hatch, they must fight their way from the nest to the ocean while facing predators from both the land and the sea. Out of the approximately 1,000 eggs laid in a nest, only 1 hatchling will make it to adulthood. Young sea turtles start on a diet consisting of mainly jellyfish and invertebrates. As they grow older and larger, they switch their diet to seaweed and algae. Green sea turtles grow very slowly, taking over 20yrs to reach their full size.
- There are 7 different types of sea turtles: Green Sea Turtle, Loggerhead, Hawksbill, Kemps Ridley, Olive Ridley, Australian Flatback, Leatherback
