In week three for STEAM we researched the different life cycle patterns observed in marine animals. We found that there are four main categories.

OVIPAROUS – producing young by means of eggs which are hatched after they have been laid by the parent.

VIVIPAROUS – give birth to live young.

OVOVIVIPAROUS – once the egg hatches, it remains inside the mother for a period of time.

METAMORPHOSIS – change of physical form, structure or substance.
