Spinyfin
Spinyfins are a family, Diretmidae, of beryciform fishes. The family name is derived from the type genus, Diretmus, from Greek, di meaning "two" and eretmos meaning "oar". They are found worldwide in deep waters, as deep as 2,000 m (6,600 ft).[2]

Timeline
gollark: ... it crashed after handling an odd emoji?
gollark: I don't know yet.
gollark: Okay, I must de some bugs.
gollark: OH NOT AGAIN.
gollark: I decided to try and copy my Amazon eböök library into Calibre. It seems that they *really* don't want anyone to do that, because due to a minefield of Byzantine file format and DRM insanity I've had to install an ancient version of their Windows client in Wine to even get ebook files in a usable format. Still to do, figure out where it keeps the encryption key. FUN!
