What is the most venomous shark?

While several shark species are known to have venom, none are considered "highly venomous" compared to other venomous animals. The venom in sharks is typically focused on prey incapacitation, rather than causing severe harm to humans. The venomous shark with the most potent venom is the dusky shark (Carcharhinus obscurus), found in tropical and subtropical waters around the world. Its venom can cause severe pain, swelling, and tissue damage. However, fatal cases due to shark venom are extremely rare.
