I know the blue ring, like the puffer fish, gets its tetrodotoxin from colonies of symbiotic bacteria. Is this the case with other cephs and do they all use tetrodotoxin or do some manufacture their own venom? and how does the toxicity of the bacteria stand up to the varieties that live in puffers and salmanders? what keeps other bacteria from colonizing the glands?
