Coconut Crabs: the world's largest anthropod. (And y'all been worrying about SPIDERS)

Well if I remember correctly, sometimes this crab is poisionous depending on its diet

Sources say yes, but they are also endangered so file them under "forbidden snacks"

Nothings illegal if nobody knows. But also you might die so there’s that

Pah. Every food can kill you, and few are as tasty as crab

That's reasonable
