| The poison in fugu is neurotoxin tetrodotoxin and although it is not always fatal, it can cause an unpleasant death. |
| The approach is illustrated with data from a predator-prey arms race between garter snakes and newts that operates through the interface of tetrodotoxin and resistance to it. |
| The highly selective sodium channel blocker, tetrodotoxin has been instrumental in characterization of voltage-gated sodium channels. |
| Brachycephalus ephippium is bright orange, and some of its skin glands secrete tetrodotoxin. |
