A close relative to the scorpionfish family, earth’s most venomous fish, is the stonefish. It releases its venom from its 13 dorsal fin spines. The fish can attack in 0.015 seconds with the poison that is capable of killing an adult within one hour. Since Europeans’ arrival on Australian shores, there have been no recorded deaths from stonefish stings in the country, despite this most venomous fish in the world hiding in the waters. However, many people have suffered stonefish stings by unintentionally stepping on them, resulting in anti-venom being created in the late 1950s to prevent the worst from happening.
