Flamboyant Cuttlefish – Metasepia pfefferi
Due to the small size of its cuttlebone, it can float only for a short time. This cuttlefish is the only species known to walk or ‘amble’ along the sea floor while rhythmically waving the wide protective membranes on their arms. The arm tips often display bright red coloration to ward off would-be predators. This behavior advertises a poisonous nature, the flesh of this cuttlefish contains a unique toxin.

A toxicology report has confirmed that the muscle tissue of flamboyant cuttlefish is highly toxic, making it only the third cephalopod found to be poisonous. Research has shown the toxin to be as lethal as that of fellow cephalopod the blue-ringed octopus.
