Stylophthalmus

Stylophthalmus (meaning 'stem-eye') was a name used for what was previously believed to be a genus of fish with eyes perched upon periscopic stalks, known in some cases to be almost one third of the length of the animal's actual body.[1] It is now recognised that all species in this genus are the fish larvae[2][3] of already named, distantly related fish in the orders Stomiiformes and Myctophiformes which may have developed this same trait as a result of convergent evolution. Thus, Stylophthalmus is an invalid name.

Stylophthalmus paradoxus, now recognized as the larval form of Idiacanthus fasciola

gollark: It's because your programs end with `error`, presumably.
gollark: Hmm, so what you're saying is that tail calls are incomprehensible dark magic.
gollark: Tail calls are where you call a function at the end of a function or something, and this is magically optimized better because something something stack.
gollark: Couldn't you just PR it to not not do that?
gollark: You can, as far as I know, emulate pcall-type stuff with temporary coroutines (which is very hacky but oh well), and those would probably not be subject to stack stuff.
