The trumpet shell Charonia sauliae has been implicated in food poisonings, and evidence suggests it contains a tetrodotoxin derivative. There have been several reported poisonings from mislabelled pufferfish, and at least one report of a fatal episode in Oregon when an individual swallowed a rough-skinned newt Taricha granulosa on a dare.

Hammerhead tetrodotoxin, which disrupts neurons’ signaling to muscles, can sicken pets if they eat the worms, according to the New Jersey Department of Environmental Protection. Direct contact ...
Fugu contains lethal amounts of the poison tetrodotoxin in its organs, especially the liver, ovaries, eyes, and skin. [4] The poison, a sodium channel blocker, [5] paralyzes the muscles while the victim stays fully conscious; [6] the poisoned victim is unable to breathe and eventually dies from asphyxiation. [7]
Furthermore, only certain species can be eaten. There have been numerous reports of poisonings after consuming mangrove horseshoe crabs (Carcinoscorpius rotundicauda) as its meat contains tetrodotoxin. [57] While horseshoe crab meat is commonly prepared by grilling or stewing, it can also be pickled in vinegar or stir-fried with vegetables. [56]
Many essential elements of how all chemical synapses function were first discovered by studying the squid giant synapse. Early electrophysiological studies demonstrated the chemical nature of transmission at this synapse by making simultaneous intracellular recording from the presynaptic and postsynaptic terminals in vitro (Bullock & Hagiwara 1957, Hagiwara & Tasaki 1958, Takeuchi & Takeuchi ...
polycyclic structures (e.g. tetrodotoxin) [5] Tetrodotoxin; compounds with a strong electron-withdrawing group attached to the acyl carbon (e.g. N,N-dimethyltrifluoroacetamide) [6] compounds with donor groups that are poorly conjugated with the potential carbonyl group (e.g. cyclol) [7]
