Opening a sodium channel causes depolarization, which could sequentially cause paralysis, heart arrhythmia, and changing the senses of heat and cold.

Ciguatoxin 1 or CTX-1 is a toxic chemical compound, the most common and potent type in the group of ciguatoxins.It is a large molecule consisting of polycyclic polyethers that can be found in certain types of fish in the Pacific Ocean.

Gambierdiscus toxicus is a species of photosynthetic unicellular eukaryote belonging to the Alveolata, part of the SAR supergroup.It is a dinoflagellate which can cause the foodborne illness ciguatera, [1] and is known to produce several natural polyethers including ciguatoxin, maitotoxin, gambieric acid, and gambierol.
This buildup of stress can cause dogs to suddenly “snap,” making it appear as if the dog’s behavior has changed out of the blue. Instead, the dog has likely been silently suffering from the ...
Afterwards, carnivorous fish, which are targeted by fishing industries, move the toxins further up the food chain.
