It was subsequently found to be quite common at depths of around 2000m in the North Atlantic, although the conspecificity of the two populations needs to be confirmed by sequanecing studies. At such deep bathypelagic depths, it can be the numerically dominant component of the halocyprid community, and as such may prove to be a useful indicator of the spread of deep water masses. The genus Metaconchoecia has been revised by Chavtur and Angel (in press) and has been made a tribe. The former species of Metaconchoecia have been divided into ten genera, and this species is now classified in a genus Deeveyoecia. NE Atlantic n Mean mm s.d.
