Classification / Names Populärnamn | synonymer | Catalog of Fishes(Släkte, Arter) | ITIS | CoL | WoRMS | Cloffa

Elasmobranchii (hajar och rockor) (sharks and rays) > Carcharhiniformes (Ground sharks) > Pentanchidae (Deepwater catsharks)
Etymology: Bythaelurus: bythos (Gr.), depths of the sea, referring to its deepwater habitat; ailouros (Gr.), cat, probably an allusion to the vernacular “catshark,” so named for its cat-like eyes. (See ETYFish);  bachi: In honor of Johann Sebastian Bach (1685-1750), a “musical genius and one of the greatest composers of all time” (so named because the senior author admires Bach and not for any Bach-like feature the shark might possess, Simon Weigmann, pers. comm.) [see also B. vivaldii]. (See ETYFish).
