The puffer fish, while popular for lampshades, is poisonous. DO NOT EAT PUFFER FISHES!
I apologize if I am offending you with this, but this made me laugh :)First of all, if the word "Poison" appears anywhere in the name, there's a pretty good chance it's not edible. For example,...
Non-edible plants are plants that are poisonous or that cannot be digested.
Salt, Water, Minerals found in your average multivitamin. You can't survive on them, obviously, but they can be ingested beneficially.
If you think about it, anything is edible as long as you can swallow it. o.o
