January 11th, 2013 Got Crabs?

While the coconut crab itself is not innately poisonous, it may become so depending on its diet, and cases of coconut crab poisoning have occurred.[45][46] For instance, consumption of the sea mango Cerbera manghas by the coconut crab may make the coconut crab toxic due to the presence of cardiac cardenolides.[47]

That's a neat trick. Hunters know that the taste of game can change due to its diet, but actually being able to pass through poisons is something I've never heard of. The closest I know of is shellfish toxicity caused by pollution.

Poison Dart frogs aren't poisonous when kept in captivity. It's called the "diet-toxicity hypothesis", and a number of critters use it.
