Pareledone is the most abundant and diverse cephalopod genus in Antarctica. It is restricted to the continental shelf and slope margins (in depths of less than 1000 m) of Antarctica and the surrounding islands of the Southern Ocean. Members of the genus tend to be small; total length reaches 95 mm (mantle length 30 mm) in the smallest species, and 350 mm (mantle length 100 mm) in the largest. The first specimens of this genus were caught in 1905, but because of the inaccessibility of their habitat there is still only limited information available on their behaviour and life history. They have no commercial value.
