Spectral Serpent
“The Spectral Serpent is an aggressive and ginormous sea serpent species located in the Brine Pool of the Desolate Deep. They possess a translucent exo-membrane covering the inside of their body, as well as 4 bioluminescent eyes. They tend to lurk deeper within the Brine Pool, where they feed on microorganisms. Despite their specific diet, they have many sharp teeth and mandibles along with their hammerhead-shaped skull, which they can use to easily fend off invasive threats. When hooked, they put up an intense fight for even the most experienced anglers.”— in-game Bestiary description

Spectral Serpent guide
The Spectral Serpent is the kind of catch that justifies a dedicated trip. This Mythical sea serpent lurks in the Brine Pool of the Desolate Deep, and you need Truffle Worm as bait, night time and clear weather to have a chance at it. The wiki describes a translucent body, four bioluminescent eyes and a hammerhead skull, and says it puts up an intense fight.
The size matches the hype: 11,000 kg on average, ranging from 6,000 kg to 27,000 kg. Its maximum weight ranks 72 among the 663 fish with a recorded maximum. It sells for about C$7,000 on average, which is 146 of the 742 documented fish, so it lands in the top fifth. The low C$0.69 per kg rate shows that the price comes from sheer mass rather than a premium per kilo. It also gives 3,500 base XP.
In the same zone, Emperor Jellyfish and Sea Mine share its Mythical rarity. Reinforced Rod and Trident Rod are both sold nearby, so you can pick up gear without leaving.
Verdict: bring Truffle Worm, wait for a clear night, and treat it as a big payday plus a large XP boost.
