The characteristics of this pterobranch species include a 1-5 mm long zoid, a collar with four pairs of tentaculated arms, a single pair of pharyngeal slits, and a solitary and sedentary behaviour.[2] It closely resembles Cephalodiscus members.[3]

gollark: Probably 3 hours at most.
gollark: Indeed.
gollark: If we look at LyricLy's diagram, it seems like it might be more than 2 hours off sometimes.
gollark: You're still not measuring actual *local* solar position, which you seemed to suggest that people needed. It's generally close, but it's affected by political factors a lot.
gollark: That's measuring it as measured from some other location which doesn't necessarily line up with actual solar position.
