Sunder-Whelp Jaw

Up to 800 kg is what the Sunder-Whelp Jaw can weigh, with a documented range of 200 kg to 800 kg and an average of 500 kg. It is a Mythical fish listed for Drylands, with Cacti Pulp as the bait and Day, Clear and Summer as its conditions, and the wiki lists it as obtainable.

Each kilogram is priced at C$9.75, which gives an average sale value of C$4,875 and a base XP of 4,800. That puts it 211th of 1,059 fish by maximum weight and 231st of 1,038 by average value, so the weight rank is the stronger of the two. The value comes from sheer mass, not from a high price per kg.

Drylands documents 25 fish in total, and three others share the Mythical rarity there: Terrosunder Skull, Reservoir Squalus and Sun-Blistered Perch. The quote reads “The juvenile, highly aggressive offspring of a apex desert leviathan. Its bite can snap ironwood oars clean in half.”

Verdict: a heavy fish that earns its value from mass rather than from price per kg, and one of only a handful of Mythical entries in Drylands.
