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.
The second edition (1955) consisted of 1,150,000 copies. The book is published by Alcoholics Anonymous World Services, Inc. and is available through AA offices and meetings, as well as through booksellers. The 4th Edition (2001) is also freely available online. Marty Mann (1904â1980) wrote the chapter Women Suffer Too in the second through fourth editions of the Big Book.
