Seisonidae
Seisonidae is a family of rotifers, found on the gills of Nebalia, a marine crustacean. Peculiar among rotifers, males and females are both present and equal in size. Males and females are similar with paired gonads. It is considered to have diverged from the other rotifers early on, and in one treatment is placed in a separate class Seisonoidea.[1] They have a large and elongate body with reduced corona.[2] Their muscular system is similar to that of other rotifers: They have longitudinal muscles as well as open annular muscles

- Seison Grube, 1861
gollark: Also, the compiler is really slow.
gollark: True to some extent, I think, but it also ends up causing me to have to do more work for approximately the same output in some areas.
gollark: Skynet was written in Rust some years back and it works perfectly with essentially zero CPU use and no maintenence.
gollark: I mean, it's excellent if I need something to be really fast or really reliable, but also very slow and annoying to write in.
gollark: I don't actually feel very productive in Rust.
