The species occurs in the subtidal zone between depths of 20 and 200 metres.[2]

Subspecies

These subspecies have been recognised:


gollark: I had one egg die from overhatcherying, so I just started only putting them in after about a day or so.
gollark: Why do you need a CB red?
gollark: I'm probably diverting views from eggs more in need, slightly, but it means that they basically always hatch.
gollark: I, personally, leave my eggs until 5 or 6 days then put them in all the hatcheries on the "list of active fansites".
gollark: I think you need about 400 UniqueViews to hatch a normal egg.
