In week there 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 of substance.
