Life cycles and growing up on the Reef

Course Access: Lifetime
Course Overview

STEMLinc Video Conferencing: Discover the life cycles of a variety of Reef animals including marine reptiles, mammals, and fish. Some Reef animals lay eggs, whilst others give birth to live young. There are different levels of parental care, and this influences how many eggs are laid, or how many babies are born.  We discuss how some offspring look very similar to their adult form, whilst others, which start their life as planktonic larvae, look surprisingly different. These planktonic larvae may undergo several changes in shape and form as they grow up to adulthood.  We will also discuss some of the environmental factors that can affect different stages the life cycles of Reef animals.

Background Information: A huge variety of fascinating lifecycles can be observed on the Great Barrier Reef.  One example is the green sea turtle. When they are about 6 years old, the immature turtles return to coastal waters, where they feed and grow until they reach sexual maturity. With their low-protein diets, this can take up to 40 years. Once the green sea turtles mature, the cycle of long-distance migrations between foraging grounds and their breeding sites begins. Green sea turtles can live more than 80 years in the wild.
