LOBSTER

The lobster is an edible crustacean of the family Nephropsidae, sub-class Malacostraca found along the coasts of the north Atlantic and the Mediterranean. The true lobsters are distinguished by having the first three pairs of legs terminating in pincers, the anterior-most pair being the largest. The average size of a lobster is about twenty centimetres in length, though larger specimens are found.
