Tectura palacea

Tectura palacea, common names the "surfgrass limpet" or "chaffy limpet", also spelled "chaffey limpet", is a species of small sea snail, a true limpet, a marine gastropod mollusk in the family Lottiidae.

The shell of this small limpet is about 6–10 mm in length and 2–3 mm in width. The shell dimensions are narrow to correspond with the limpet's habitat: the narrow blades of surfgrasses in the genus Phyllospadix, found at low tide levels. This species occurs in the Eastern Pacific Ocean, on the coast of North America, from Vancouver Island, British Columbia to northern Baja California, Mexico.[1]

The habitat of Tectura palacea is the blades of surfgrasses in the genus Phyllospadix

Feeding habits

These small limpets graze on the film of microscopic algae that covers the leaf blades of the marine plant Phyllospadix. As can be seen in the accompanying photos, the limpet scrapes off this algal film, leaving a clear trail on the surface of the blade behind it.

gollark: > The 22 nm node may be the first time where the gate length is not necessarily smaller than the technology node designation. For example, a 25 nm gate length would be typical for the 22 nm node.
gollark: As far as I know it *used* to actually be a measure of something, but they hit issues around... 22nm or something, don't really know... and despite said measure not changing very much the processes kept getting better, so they just reduced them.
gollark: I mean, generally if the number goes down the density of the transistors goes up, but it's not an actual measurement of anything.
gollark: They don't correspond to any actual measurement now.
