Crab larvae develop in open water, not near the reef where they started their life. Fertilised crab eggs are released into the water and float with the currents while they develop into the larval form. They find their way back to suitable habitats from long distances.

The life cycle of eels has long been a mystery. The eels breed only once at the end of their life cycle. In the autumn, adult eels leave the rivers and streams and head for the ocean. From there, they make a long journey of thousands of kilometres to a place somewhere in the South Pacific ocean. Scientists think the spawning grounds may be close to Tonga.

During its life cycle, the green-lipped mussel undergoes enormous changes, including fundamental changes in shape. It changes from a free-swimming larval form (which swims in the ocean) to a settled juvenile and adult form (which is anchored to one spot).

Whitebait lay their eggs in freshwater, and after hatching, the larvae are swept down to the ocean where they grow. The young then move back up into freshwater in large shoals known as runs.

Humans have many reasons to grow plants: for food, for building materials or simply for pleasure. A plant really just has one reason to grow – to reproduce to make more plants like it.
