(1995) from shallow hydrothermal vents and by Simboura and Zenetos (2005) from a depth of 1250 m. Commonly distributed in deep sea habitats of the East Pacific, the Chukchi Sea and possibly the Bay of Biscay ( Simboura and Zenetos 2005 ), thus the record by Dando et al. (1995) is considered questionable as it is from a shallow-water habitat.
