Vulcanocalliax arutyunovi is a
species of
Thalassinidea (a ghost shrimp or mud lobster) found on a
mud volcano in the
Gulf of Cádiz between
Spain and
Morocco. It was discovered during the
Census of Marine Life, and is so distinct from its closest relatives that it has been placed in a new
subfamily, the
Vulcanocallianacinae. The species is unusually large for a ghost shrimp, but despite that appears to brood only a single
embryo. The species is named after the volcano on which it was discovered,
Captain Arutyunov.
