Dikwa andresi , a new amphipod crustacean (Dikwidae) from the Scotia Arc
The new amphipod crustacean species Dikwa andresi from the Scotia Arc is described in detail. This is the first record of the family Dikwidae in the Southern Ocean. The white species was caught in water depth of 270–290 metres during the Antarctic autumn, living on the red hydrocoral (Hydrozoa) Erri...
