The number of hooded hooks and the posterior extension of the metameric dorsal ciliated organ are size dependent. Smaller specimens with about 35–45 chaetigers possess 6 neuropodial hooks on average whereas larger specimens with about 55–60 chaetigers have 9 hooks. A positive correlation between the posterior extension of the metameric ciliated organs and the size of the specimens could also be found in this species. It reaches chaetiger
