The first topic that must be considered is the
name. Crayfish is the term most often used in
technical literature and the name used in this
document. However, these same animals are
also known as crawfish, crawdads, and
mudbugs. Rest assured, regardless of the name,
they all refer to the same broad category of
animals. Specifically, they are freshwater
decapod crustaceans, the freshwater equivalent
of shrimp and lobsters.
