Females deposit their eggs in the safety of the coral, as many as 200.
Cuttlefish have a short life-span. The male and female will both have died by the time the baby cuttlefish hatch in four months time.
The cuttlefish are utilised in many different ways. They are the origin of sepia ink, they provide nutrients for our birds and a rough surface to sharpen their growing beaks, they are delicious to eat and their cuttlebone can be used to cast silver jewellery.
Overfishing and pollution are a serious threat to cuttlefish populations because the cuttlefish are so short-lived and only spawn once in a lifetime.
The US military is currently studying cuttlefish's disguising abilities to research advanced cloaking armour.
This brings us to the end, but don't stop here! You've seen how amazing cuttlefish are.
