Polished Crab

The polished crab lives burrowed in sandy sea bottoms. It looks for food between the grains. Because polished crabs don't live close to the coast, they are generally only found after storms and sand nourishments, washed up onto the shores. The small carapace of these crabs is surrounded by a rim of hair. In Dutch, they are called 'nail crabs', because its carapace resembles the nail of a bit toe.

  • Distribution and habitat

    The polished crab lives at depths down to 45 meters, although there have even been reports of 110 meters. This species is not found very often due to its tiny size and the manner in which it lives. Therefore there is relatively little known.
