Description
Hartmania moorei is a short-bodied scale worm with about 35 to 37 segments and 15 pairs of elytra. The elytra are large and cover the dorsum completely; they have large tubercles on the surface. The prostomium is bilobed and deeply divided anteriorly with a pair of cephalic peaks with rounded tips. The lateral antennae are inserted ventrally, directly beneath the median antenna ceratophore, and the styles of all antennae have slender papillae. The Parapodium is elongate and tapering. The Chaeta are about as thick as the Chaeta and all chaetae have serrations in transverse rows and sharply pointed unidentate tips. Neurochaetae with bidentate tips are also absent.
Biology and Ecology
Some specimens of Hartmania moorei have been collected from the tubes of Nereididae polychaetes such as Alitta virens and is likely to have a commensal relationship with them.
