What the name means
Acantholophius lucerna means roughly “lamp spine-crest”: from acantho- (spine) and lophius (crest), and lucerna (lamp). 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 the vent floor (it opens at diving level 40) and look for an angler with Lantern Deep 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.
