Which cuttlefish species is recognized as highly toxic and actively venomous?

Answer

Flamboyant Cuttlefish (Metasepia pfefferi)

The Flamboyant Cuttlefish, scientifically designated as *Metasepia pfefferi*, represents the most significant immediate hazard mentioned among cuttlefish species. This specific creature is characterized by being highly toxic and, crucially, venomous. The designation 'venomous' implies an active mechanism where the animal injects toxins, often used for defense, distinguishing it from species that merely contain passive toxins. Reports indicate that the toxins carried by these small, vividly colored marine animals possess sufficient potency to be lethal to humans, contrasting sharply with the hundreds of other cuttlefish species globally consumed as safe seafood.
