    Crabs

    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.

    Eels

    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.

    Green-lipped mussels

    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).

    Human beings

    Find out about the key stages in the development of a human.

    Inanga (whitebait)

    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.

    Insects

    Scale insects are tiny in size but have a significant impact on the forest ecosystem.

    Glow-worms spend most of their lives as larvae – where their famous light is produced most brightly. The other stages are surprisingly short in comparison.

    Moths

    Find out how to rear moths using basic equipment such as a plastic lunchbox to grow eggs and caterpillars into moths.

    Plants

    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.
