Eunoe oerstedi is a scale worm which is widely distributed in the Arctic Ocean, North Atlantic Ocean and North Pacific Ocean from shallow waters to depths of about 950m.[2][3]

Description

Number of segments 37; elytra 15 pairs. No distinct pigmentation pattern. Prostomium anterior margin comprising two rounded lobes. Lateral antennae inserted ventrally (beneath prostomium and median antenna). Elytra marginal fringe of papillae present. Notochaetae distinctly thicker than neurochaetae. Bidentate neurochaetae absent.[4]

Taxonomic comments

Eunoe nodosa and E. oerstedi are very similar and both species occur in the same regions. The two species differ in the ornamentation of the elytra, which are covered with very small nodular tubercles in E. nodosa while in E. oerstedi the tubercles are spiny.[3]

gollark: The trouble with saying that lifesaving medicines shouldn't cost loads is that developing and testing new medicines is *very expensive*, and for rare conditions that's not split across many people. That only applies in *some* cases, though.

gollark: "Great" if you like what's effectively cosmic horror, I suppose.

gollark: <@!336962240848855040> There's a great series of SCP Foundation stories about "antimemes", which are sort of what you're talking about: http://www.scp-wiki.net/antimemetics-division-hub

gollark: Ah yes, "security", because Apple's designs are perfect and those who change them will merely destroy that perfection.

gollark: I... don't really think it's bad at all, really.
