Sea wasps are a type of jellyfish known for their potent venom. They belong to the box jellyfish family and are primarily found in the warm waters of the Pacific Ocean and Indian Ocean. Their transparent, cube-shaped bodies can be difficult to spot, making them a hidden danger for swimmers and divers. These creatures have long, trailing tentacles that can deliver a painful sting, which may cause serious health issues or even be fatal to humans. Despite their beauty, sea wasps are best admired from a distance, as their sting can lead to severe reactions and requires immediate medical attention.
