Hermadionella nipponicus explained

Hermadionella nipponicus is a scale worm known from Japan in the north-west Pacific Ocean from the intertidal zone.^[1]

Description

Hermadionella nipponicus has up to about 64 segments with 15 pairs of elytra, which bear a fringe of papillae. The lateral antennae are positioned ventrally on the prostomium, directly beneath the median antenna (almost completely obscured in dorsal view). The prostomium also bears a pair of acute anterior projections on the anterior margin. Notochaetae are about as thick as the neurochaetae, and the neurochaetae bear bidentate tips^{[1] [2]}
