Did you know that tetrodotoxin is more potent than cyanide and is not destroyed by cooking? This lethal neurotoxin is most famously found in pufferfish, but many other surprising marine and terrestrial animals also contain tetrodotoxin and pose a significant risk to humans if consumed.

While most people are curious if cuttlefish are safe to eat, research confirms that the vibrant flamboyant cuttlefish (*Metasepia pfefferi*) is indeed toxic, possessing a powerful neurotoxin in its muscle tissue similar to the blue-ringed octopus. This fact, however, does not apply to the common cuttlefish varieties widely consumed in a nutritious diet.
