Of the almost 30,000 species, it seems that around a quarter have abandoned their stomachs, including groups like wrasse, carp, cowfish, pufferfish, zebrafish and more.
Marine life is in abundance, including trigger fish, moray eels, angelfish, butterfly fish, groupers, parrotfish, wrasses, scorpionfish, pufferfish, damselfish, rays, snappers, green sea turtles, hawksbill turtles, and dolphins.
Pufferfish that are born and grown in captivity do not produce tetrodotoxin until they receive some of the poison-producing bacteria, often by eating tissues from a toxin-producing fish.
