Rissoina meteoris is a species of minute sea snail, a marine gastropod mollusk or micromollusk in the family Rissoinidae.[1]

Description

The height of the very slender shell varies between 5.5 mm to 9.0 mm The protoconch consists of 1.25 whorl, and the teleoconch of ca. 10 very flat whorls. The protoconchis smooth, the teleoconch apparently smooth and glossy but with tiny punctures visible only under very high magnification, densely set in spiral bands. The aperture is piriform, channelled at the insertion of outer lip on the previous whorl. The outer lip is definitely opisthocline, thickened but not demarcated from the body whorl, with rounded edge, inside slightly swollen near parietal insertion [1]

Distribution

This species is found on the Great Meteor seamount in the northeast Atlantic at a depth of 470 m.

gollark: Strassen, then?

gollark: I assumed that the only entry not doing that (or calling out to external stuff which did ???) was mine, which did an equally inefficient algorithm in a weird recursive way.

gollark: Really? Interesting.

gollark: Naive matrix multiplication.

gollark: Slightly wrongly, but oh well.
