The sproke shark (Isistius sprokerino) is a species found almost exclusively in Fremont river, Utah, but mostly near Capitol Reef national park. They are on average 27cm in length and a diameter of 7.5cm at the mouth, which is just larger than their natural food source, the Sproke can. They are thought to be a species of cigar sharks which migrated to the Pacific northwest over time and had to adapt to the rapid rise in human Sproke pollution; this explains why they are among the only fish capable of breathing and/or consuming Sproke.
They are a vital part of Capitol Reef's ecosystem: by drinking Sproke and using their metal-cutting circular array of teeth to eat leftover cans, they filter Sproke from the water which is toxic to other animals in the area. Their diet is also a defense mechanism against predators, who are poisoned upon trying to eat them; however, the sproke shark's main predator, the Fingerboy, has evolved an immunity to Sproke poisoning.
Local soyentists fear they may go extinct due to efforts of reducing littering and Sproke pollution, thus diminishing their food source. However, some argue the subspecies Isistius sprokerino lacus (sproke shark of the lake) which instead uses its serrated jaws to hunt heavily armoured shellfish, will remain a survivor.
