Here is an old drawing by  epeon that I finally got around to upload. I just really love how this came out. The perspective and the water reflection just are special to me.
Also here is my fluff text for it, all the way back from 2022 according to my files.

Swampy’s lemon shark

That lemon shark had had no business being this far up the murky rivers instead of the coral reefs it came from. Lost and probably very confused, the shark was currently in the middle of being moved to a location where its kind was more common: A reptile’s digestive tract. Granted, Swampy was an alligator and not a saltie, but it was all the same to the shark which tried its best to struggle free from his grip. Though with the sweetwater playing tricks on its metabolism, the shark was unable to put up much of a fight as the alligator did not even bother to drag the weakened creature to shore, opting to devour it whole and alive in the middle of the river instead. Ever since he had grown large enough to flip the food chain on them, Swampy had loved sharks. They were slender, flexible and packed with nutrients that digested without any annoying fur, collars or debris like turtle shells or thick bones. Once he subdued one they were good eating for the car sized alligator. Swampy had taken the occasional nurse shark in his time as well as a bunch of mostly juvenile bull sharks, which were the best at handling low salinity and thus a natural part of his diet. This one tasted entirely different though. Swampy wondered if he had caught a new species he had never eaten before or just a particularly sick individual. Another swallow brought the shark deeper into his body, his flexible collar stretched tightly around his swollen neck as the kicking tail of his prey made quite the impression. Swampy came to the conclusion that food was food and so far any species of whatever kind that entered his stomach had melted in the end. And sharks were always a lovely treat that gave his stomach little trouble.
One swallow after another brought the lemon shark closer to just that inhospitable spot in the alligator’s body. Its pectoral fins were folded to its sides and then it got a last look past closing yellow teeth before a strong suction from the feeding reptile’s throat consumed it. A few more contractions of Swampy’s neck caused the bell on his collar to mutely dangle in the water while the shark was forced to curl up into a ring of doomed but nutritious meat sitting in an acidic vat populated by a few pebbles and bleached dog collars. After his successful hunt Swampy swam over to Billy’s rowboat, nearly capsizing it as he pulled himself inside, where he promptly flopped on the wooden floor, showing off how his well occupied belly swelled to both sides as he laid down on it. “Filled your belly already?” asked the smiling man as if expecting an answer. “Then I can start my fishing now without you stealing everything?”
