Propebela scalaris is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.[1]

Description

The length of the shell varies between 11 mm and 27 mm.

The shell is elongate. The spire is longer than the aperture. The spiral striation is closer, and more uniform than in Propebela rugidata. The apex is rounded acuminate; on the first whorl, only faint spiral ribs (2–3) are visible.[2]

gollark: *How* awesome?

gollark: Muahahaha, indirect move operations.

gollark: So you can use MEZ for other things.

gollark: They are in general. My thing just has the program counter be the last region of memory.

gollark: Not currently. I was going to add `IMOV` or something, but forgot. You can technically just do self-modifying code quite easily anyway.
