Question: are dead porcupine fish spines poisonous?
Answer: Porcupine fish are relatives of the Tetraodontidae, what are generally called Pufferfish. ... If you stepped on spikes that were big enough to hurt, you probably stepped on a Porcupine fish (Diodontidae), which is actually not poisonous (bad to eat) or venomous (going to inject you with something bad).
