What the name means

Diploserranus atramentaria means roughly “inky double-saw”: from diplo- (double) and serranus (saw), and atramentaria (inky). 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 midnight water (it opens at diving level 10) and look for a grouper with Abyss Ink 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.
