Arctosa cinerea

Arctosa cinerea is one of the most conspicuous wolf spider of central Europe, with a palearctic distribution and also found in Congo.[1] The spider reaches a length of 17 mm (males only 14 mm), and occurs only on sandy beaches of rivers, lakes and oceans. Its grey-brown color makes for a good camouflage, and so it is not often seen, even if it wanders around during daylight. They dig holes in the ground, which they cover with silk, or hide under rocks.

Name

The species name cinereus is derived from Latin cinis ash, meaning "ashen".

gollark: And I don't think it'll be shifted significantly by being able to deal with that kind of rare event much better as much as... blind luck, happening to have had relevant opportunities, social skills and intelligence.
gollark: Evolutionary fitness is also not the same as physical fitness.
gollark: That's plausible I guess, but it's possible that many of those could have been avoided (and your definition would count this as "fitness", even). I'm pretty sure it's still less common than, well, other day to day bad things.
gollark: Are those *common*? I don't think I know anyone who's actually experienced any of those. Except maybe animals, very broadly.
gollark: I mean, most common bad situations are going to be along the lines of "someone was rude to me at work" or "my car broke down", not "I must run away from a thing very fast" or "I have to lift a several hundred kilogram object for some reason".
