Stone crab (Eriphia spinifrons), the largest crab in the Black sea. The width of his shell 9-10 cm Prefers to live deep, although often found near the shore, but it is only in the desolate stony places. If all benthic crustaceans are primarily scavengers (character power), stone crab, strong and aggressive, can be fast and agile predator. In the ambush he laid for snails, worms and small fish. His claws possess enormous power – click, like sunflower seeds, the shells of mollusks and hermit crabs. Their muscle fibers at the molecular level differ from the muscles of animals and man (not in our favor). The color of the shell of the stone crab are always the same as the stones among which he lives. Basically it is a reddish-brown color, but the stone crabs living among the yellow sandstones themselves are quite bright.
