Nemertea is a phylum of animals also known as ribbon worms or proboscis worms, consisting of about 1300 known species. [2] [3] Most ribbon worms are very slim, usually only a few millimeters wide, although a few have relatively short but wide bodies. Many have patterns of yellow, orange, red and green coloration.

The sexes are separate in this species. The females lay eggs which are fertilised externally and develop directly into juvenile worms. [2] This ribbon worm is diurnal and makes little attempt to avoid predation. It is possible that its bright red colouration is aposemetic, giving warning that this particular ribbon worm is toxic or unpalatable. [6]
