Depth range Planktonic in the water column over a 50 m deep sand bottom. "The specimen was found [...] in the upper-net sample which was, however, much contaminated with the upper water during the drawing up of the Dragonet. Thus, the exact level at which the present Rostraria was caught is quite uncertain."

Status Rostraria bierii Tokioka, 1970 has been re-evaluated by Mortimer, Mills, & Gil (2022) as an indeterminable Magelona head, not an amphinomid rostraria larva. [details]
