Australian giant cuttlefish, is the world’s largest cuttlefish species, growing to 50 cm in mantle length and over 10.5 kg or 23 lb in weight, they use special cells in their body to change their colour in an instant. They use these colours for protection when they wish to hide and the males use these different colours to attract a female, they can form beautiful coloured patterns of just about every colour of the rainbow.
They have a very short life span of 2 to 3 years. Because of their short life span, the cuttlefish reach maturity in around eight months. Their diet consists of fish, crabs and shrimp.
The cuttlefish has eight tentacles, two have sucker-pads, and before catching their prey they usually change colour to hide, then they use their long tentacles, once the prey is caught the cuttlefish then brings the prey to its mouth, the cuttlefish have a very strong sharp beak which they use to break the shells if they have caught such things as crabs. When not catching prey, their tentacles are retracted.
