General Description

In members of this genus the proboscis is forked, with the terminal branches shorter than the basal part (other spoon worms in this part of Australia have unbranched proboscis). Body up to about 8 cm long.

Biology

Spoon worms were previously classified in their own Phylum: Echiura. However, recent DNA studies have shown that these worms are modified polychaetes with very reduced chaetae and segmentation and they are now grouped in the Phylum Annelida.
