Description

The length of the shell varies between 8 mm and 24 mm.

W.H. Dall considered this originally as perhaps a variety of Bela laevigata (synonym of synonym of Obesotoma laevigata (Dall, 1871)). It is pure white, with distinct revolving lines decussated by regular lines of growth. Only one specimen of this description was found, which is even more globular than the typical form, and has a deeper sinus and narrower aperture. It may be distinct.[2]

Distribution

This marine species occurs in the Sea of Japan, the Bering Sea and off Alaska (Point Barrow, Arctic Ocean, to the Shumagin Islands).

gollark: <@312031356169224203> <#482370338324348932> is limited to 1 message per 5 minutes, so seriously, what *are* you on about?
gollark: I do wish the internetworking companies would just use some sort of scheme of limited bandwidth with some allowance for short peaks instead of data caps, which would match closer to what the actual constraints are.
gollark: Though over here they're mostly just used on mobile phone connections, not home ones.
gollark: Data caps do kind of work well at getting people to use less *bandwidth* because people don't use their internet connection as much, but they don't actually have some finite amount of internets or something weird like that.
