This species burrows into muddy or muddy sand substrates at depths of from 10mto130mm (30feetto430feetm) and is frequently found in association with the Norway lobster Nephrops norvegicus. This species can reach a length of 13cm (05inches) TL. The specific name honours the Swedish zoologist Bengt Fredrik Fries (1799-1839).[1]
