The first Acanthomuraena ferruginea ever found, swimming live. Its hidden genes stay hidden.

Acanthomuraena ferruginea lyrilata is a species of alien fish in Fish of Ganymede: an eel with a spiky dorsal fin, Rust Vent colouring, a lyre tail and a wide mouth. It lives in hadal trenches, 25 km to 60 km under Ganymede’s ice. It was first found by KelpDiver78 on 6 November 2026.

What the name means

Acanthomuraena ferruginea means roughly “rust-coloured spine-moray”: from acantho- (spine) and muraena (moray), and ferruginea (rust-coloured). 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 eel with Rust Vent 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.
