• Norwegian: dverghummer


The male does not grow bigger than 4 cm in length, the female may reach 3 cm. It lacks the blue stripes of the G. strigosa, but it could be confused with the G. dispersa. The latter has a more narrow and pointed rostrum. G. nexa has more hair on the first pair of legs and wider rostrum (horn in the forehead). The first pair of legs have distinct spikes on the second joint. G. nexa and G. dispersa were long considered to be the same species.


Can be found from the subtidal zone, but is more frequent deeper than 15 meters. It seems to prefer rocky or sandy substrate.


G. nexa can be found along most European coasts, from Norway to the Mediterranean.
