Stonefish

Stonefish is an incredibly venomous fish living in tropical waters mostly off the coast of Australia and parts of the US. It can cause pain that only escalates with time. Eventually, the pain will subside but even after the barb is removed, patients have reported increasing pain more than 12 hours later. Without antivenom or denaturing the venom with excessive heat, the pain builds and builds until the patients request euthanasia. Its spines hold the venom, hidden in its dorsal fins. Aboriginals living around the Great Barrier reef have “corroborees,” large gatherings, and will during these gatherings hold reenactments of people being stung by this monster (either for amusement, learning, or both).
