This email is going around: "Do not eat these mini lobsters. These mini crustaceans are literally the garbage cleaners in the sewage treatment plants. The "dirtier" the water, the fatter these mini lobsters become. Their lungs are full of worms and their flesh saturated with poisonous metals."
Is this true?
Siva gives a detailed explanation on the nature-singapore mailing list of the facts behind lobsters.
