[originaltext]A poisonous fish which has a sting strong enough to kill a human

A poisonous fish which has a sting strong enough to kill a human is invading the Mediterranean, warn scientists. The International Union for Conservation of Nature has raised concerns after the poisonous fish was spotted in the waters around Turkey, Cyprus, and the eastern Mediterranean. Native to the South Pacific and Indian Ocean, the potentially deadly fish has poisonous hooks and a painful sting capable of killing people. Although fatalities are rare, the stings can cause extreme pain and stop people breathing. The fish, often known as Devil Firefish, is a highly invasive species, and environmentalists fear its arrival could endanger other types of marine life. After being spotted in the Mediterranean, a marine scientist says, “The fish is spreading, and that’s a cause for concern.”
