Additional Information
  • May be confused with Pomatoceros lamarcki, the tube of which differs from Pomatoceros triqueter as it has two vestigial ridges, one on each side, in addition to the median keel. Further differences can only be seen when the worm is removed from its tube (Hayward & Ryland, 1995). Further distinction between the two species can be obtained by using biochemical genetics, as described by Ekaratne et al. (1982).
  • Males are cream in colour whilst females are bright pink/orange in colour (Thomas, 1940).
