What the name means
Acanthoregalecus aurea means roughly “golden spine-king of the herrings”: from acantho- (spine) and regalecus (king of the herrings), and aurea (golden). Every species name is built from its genes: the dorsal fin and body plan give the genus, the colouring gives the species name, and the tail and mouth the last word.
How to find one
Dive to hadal trenches (it opens at diving level 28) and look for an oar with Brine Gold colouring, or breed for it: you need all five of its traits to show at once, and some of them may be recessive, hidden in a parent’s second gene copy. The breeding screen shows the exact odds. See how fish genetics work.
