Lobsters are invertebrates, members of the Class Crustacea of the Phylum Arthropoda. This class includes animals without backbones and with hard shells like crab, shrimp, crayfish, water fleas and wood lice. A male lobster is called a cock and a female a hen or chicken (when she weighs about 1 pound).
The Big Book serves as the basis of Alcoholics Anonymous (AA). It contains the 12 steps that are at the core of the Alcoholics Anonymous program, as well as stories about alcoholics who have been through the recovery process.
These sound familiar to anyone who has read the Twelve Steps of Alcoholics Anonymous written by Bill Wilson a few years later. The Oxford Group meetings and principles were the means by which Wilson stayed sober for the winter months of 1934 until a failed business trip he took to Akron, Ohio.
