Owen Anderson, Fisheries Oceanography II
This is a stunning photo of Pelagonemertes rollestoni Moseley, 1875, an unusual midwater example of the phylum Nemertea – the ribbon or proboscis worms. This specimen was collected on the Chatham Rise and was the first record of this species to be found in New Zealand waters.
