The genus Strigamia is readily recognised by the presence of a prominent 'tooth' at the base of the poison claw. This species is very similar in appearance to the inland S. crassipes, but differing in subtle morphological characters and, characteristically, in it's seashore habitat.
Distribution and Habitat
An exclusively coastal species, occurring near the high water mark around the entire coastline of Britain and Ireland. Often numerous when found in shingle, but also under stones and in rock crevices.
