Venom can be fatal for demonic-faced fish

Devil face fish can release venom that causes heart failure when the victim touches the spike on its back.

Dr. Jamie Seymour, a toxicologist at the Fisheries Research Institute, James Cook University, Australia, tested the venom extract of stonefish , the most exclusive fish in the world, in the video posted on YouTube on June 26, according to SmarterEveryDay.

In the video, when Dr. Seymour pressed a spiky sponge on the back of a demon-faced fish, a stream of liquid immediately shot up. Seymour said the devil's fish venom can be extremely painful and death from heart failure. Devil face fish use this venom to defend themselves from the hunter.

The poison of the devil's face lies in poisonous pockets hidden under 13 sharp spines on its back. When humans touch these poisonous spikes, the poison bag is compressed, releasing the poison. Poison bags will be added after about 2-3 weeks if the animal is hunting.

The poison of demon-faced fish after being extracted from thorns is sent to CSL biotechnology company to prepare antidote. Every year, hundreds to thousands of people trampled on this poisonous fish on Australia's east coast.

Demon fish are 30–40cm long, good at camouflage and use speed to hunt. After the fish determines its prey, it bounces in just 0.015 seconds to swallow the opponent.
