This is one of our most destructive wood-eating Crustacea. It 
is commonly associated with Limnoria legurium, but fortunately 
for our piles and pier woodwork, it is not prolific as the smaller 
Limnoria. It has been found to destroy a piece of sound timber 
thirteen inches square in less than ten years. It eats into the 
timber in a level with the mud to the usual height of neap tides, 
avoiding, however, the knots in the wood. In this manner the 
wood is riddled in every direction, and is then easily destroyed 
by the force of the waves.
