Summary

Description

The body of Notomastus latericeus is between 15 to 30 cm long, and is divided into between 100 and 150 segments. The anterior region of the worm is purple or dark red, becoming brighter or yellowish posteriorly. In general, the posterior region of the animal is colourless or transparent.

Identifying features

  • Between 100 to 150 segments, and between 15 and 30 cm long.
  • Anterior region of 12 chaetigers with reticulated appearance, all of which have chitinous bristles (capillary chaetae) projecting from the parapodium.
  • Paired genital pores on the dorsal surfaces of many anterior segments of posterior region.
  • The posterior most division of the three divisions of the body (pygidium) terminates in a membranous flap.
