Sipunculid worms

NIWA
This selection of sipunculid worms were found in muddy sediment in the Kaikoura canyon at 1079 m deep. They are recognisable from their little tube or siphon that use to collect their food (organic detritus from the surrounding mud and water), and their lack of segmentation or bristles.
