Cuttle Fish

I took this photo while snorkeling in the Caribbean.
Cuttlefish are marine animals of the order Sepiida. They belong to the class Cephalopoda, which also includes squid, octopuses, and nautiluses. Cuttlefish have a unique internal shell, the cuttlebone. Despite their name, cuttlefish are not fish but molluscs.

Toxicity
Like octopuses and some squid, all cuttlefish are venomous. The genes for venom production are thought to be descended from a common ancestor.

The muscles of Metasepia pfefferi (the flamboyant cuttlefish) contain a highly toxic unidentified compound. 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.
