Apex Leviathan guide
Apex Leviathan is the sort of catch you read about rather than land. This Extinct fish lived in the Open Ocean of the Second Sea, appeared in Foggy weather to anglers using Luminous Larva, and was tagged as a Hunt fish. It is now Unobtainable.
Its stats are huge. The weight ranged from 300,000 kg up to 2,100,000 kg, averaging 650,000 kg, and that maximum ranks 12th of 663. The average sale of C$130,000 puts it 19th of the 742 documented fish, so it sits near the very top of the market even though the price per kg is only C$0.20. It gave 400,000 base XP, one of the largest figures in the Fisch data.
Six other Extinct fish are listed for the same zone: Black Swallower, Four Eyes Fish, Pelican Eel, Psychedelic Frogfish, Rock Gunnel and Sea Leviathan. Compared with them, this one was the headline catch.
Verdict: there is nothing to prepare for. If your inventory somehow holds one, it is worth a fortune compared with the 742 documented fish; if not, it is simply a record of what the Second Sea once offered.
