Tetrodotoxin—a ghastly way to go!”

Ciguatoxin is a powerful neurotoxin produced by a tiny organism, a dinoflagellate called Gambierdiscus toxicus, which lives among the algae that grow in channels on the coral reefs. Herbivorous fish feed on the algae, and carnivorous fish in turn feed on them, so the toxin accumulates in large, predatory fish like snapper, grouper, surgeonfish, and jack (all of which I saw on the menu). The ciguatoxin causes no illness in fish—they seem to thrive on it—but it is very dangerous to mammals, and to man.

There is no way a fisherman can tell whether a particular fish is toxic, and no way of preparing or cooking it that will deactivate the toxin.

We have millions of these brown, tree-climbing snakes everywhere—the whole island is overrun by them. They climb the telephone poles, get into the substations, through the ducts, into the transformers, and then, pfft! We have another outage. The blackouts can happen two or three times a day, and so everyone is prepared for them—we call them snakeouts.

“There is no birdsong on Guam—the island is silent,” John said. “We used to have many birds, but all of them are gone—there is not a single one left. All of them have been eaten by the tree-climbing snakes.”

The tree-climbing snake had made its way to Guam in the hold of a navy ship toward the end of the Second World War and, finding little competition among the native fauna, had rapidly multiplied.

he would have to be picked up and lifted (“like a corpse,” he said) into the car; but once there, and seated at a card table, he could play a fast and hard game of gin rummy. He could not start the play—someone else had to do this—but once the first card was slapped down, he would suddenly come to life, respond, pick up another card, and continue the game.

BMAA might have two distinct effects: given in high doses, it caused an ALS-like condition to develop rapidly; but smaller doses seemed to cause, after a considerably longer period, a parkinsonian condition—a double action reminiscent of the Guam disease.
