Abstract
Hurley and McKnight1 have reported that the pelagic tunicate Pyrosoma atlanticum atlanticum rests on or swims just above the sea-floor at a depth of 160–170 metres. Indirect observations made on this species in the course of a line-fishing survey of the fishes of the south-eastern Australian continental slope2 corroborate the concentration of this species near the sea-floor and extend the habitat to the floor of the continental slope.
