Stone Fish

Stone Fish get its name from how they seem because when they're swimming, it's easy to mistake them for a lone stone on the ocean floor. However, if someone were to make this error and then happen to tread on one, they would probably end up in the hospital, and that's assuming they're lucky. While it's debatable whether stone fish are the most dangerous fish in the sea—the term "poisonous" can refer to a variety of things—they undoubtedly rank among the worst.

Due to their exceptional camouflage, stone fish species are typically found in habitats near the ocean's bottom in the Indo-Pacific area. Although a bite is a genuine risk if you step on them, they are not particularly violent toward large species they can't reasonably eat, like humans.

Due to the widespread availability of an efficient antidote close to the stone fish's natural habitats, there haven't been many deaths from stone fish bites, but they have the potential to cause significant harm if untreated. Within hours of being bitten, stone fish venom can result in paralysis, tissue necrosis, heart failure, and even death.
