The Challenge

The 5th in our new challenge layout catering for all aspects of nature for us nature lovers.

As you can see the title will start with the category which will make it easier for me when choosing what challenge to do next, I can see the challenges I have already run in this category.

For this challenge please add your images of CUTTLEFISH.

Interesting Facts

> Despite their name, cuttlefish are not fish but molluscs.

> Cuttlefish have an internal shell (the cuttlebone, probably better known as the tough material given to parakeets and other caged birds as a source of dietary calcium.), large W-shaped pupils, and eight arms and two tentacles furnished with denticulated suckers, with which they secure their prey.

> Recent studies indicate that cuttlefish are among the most intelligent invertebrates.

> The Greco-Roman world valued the cephalopod as a source of the unique brown pigment that the creature releases from its siphon when it is alarmed. The word for it in Greek and Latin, sepia (later seppia in Italian), is used to refer to a brown pigment in English.

> Cuttlefish are sometimes referred to as the chameleon of the sea because of their remarkable ability to rapidly alter their skin color at will. Cuttlefish change color and light polarity to communicate to other cuttlefish and to camouflage themselves from predators.

> The blood of a cuttlefish is an unusual shade of green-blue.

> The muscles of Pfeffer’s Flamboyant Cuttlefish contain a highly toxic compound that is yet to be identified.2 Mark Norman with Museum Victoria in Victoria, Australia, has shown the toxin to be as lethal as that of a fellow cephalopod, the blue-ringed octopus.
