Sabre-tooth fish injects predators with heroin-like venom

Sabre-tooth fish injects predators with heroin-like venom

Of the 100 fang blenny species in existence, only 30, which belong to the genus Meiacanthus, have venomous glands, which suggests that their fangs developed before their venom glands, which is unusual, says study co-author Nicholas Casewell from the Liverpool School of Tropical Medicine.

While the study could not rule out the bite caused pain in fish, it seemed plausible the neuropeptide and opioid components may cause a sudden drop in blood pressure. What makes the fish's story even more remarkable is the fact that, unlike most poisonous creatures, the Fang Blenny evolved their fangs before their venom.

And when the researchers injected lab mice with the venom, the mice experienced zero pain. They were a neuropeptide that occurs in cone snail venom, a lipase similar to one from scorpions, and an opioid peptide. Generally speaking, when it comes to fish with venomous spines or other animals that are venomous, the bites of the animals or getting poked by their spines is described as being extremely painful.

The fanged fish's heroin-like venom could lead to pain treatments.

But upon closer inspection, scientists discovered that fang blennies have a trait unlike any other animal.

And while the team does not expect to develop new pain medications based on this discovery, Dr Casewell said it revealed just how much is still hidden in coral reefs, which are under threat around the world as sea temperatures rise. That might not seem like a great defensive move, but with fang blennies, the bites are laced with opioids, disorienting potential predators of the fish long enough to allow them to make a getaway. The fish were then returned to the tanks and the swabs were suspended in a solution to draw out the venom. "The venom causes the bitten fish to become slower in movement and dizzy by acting on their opioid receptors". "The venom causes a drop in blood pressure probably from the presence of these peptides".

Being small, fang blennies are constantly under threat from any predator that can gobble them up whole. The blood pressure of the mice, however, plummeted by almost 40 percent. Dr. Casewell stated that the predatory fish tried to eat the fang blennies.

These "deceitful imitations", the study authors said, are practicing mimicry, an evolutionary strategy that drives species to look like other species sharing their habitat that have better defenses against predators - such as toxins.

For the study, the researchers analyzed venoms extracted from fang blennies. He explains that although the feeling of pain is not produced in the victim, the opioid components from the venom can produce sensations of unpleasant nausea and dizziness in mammals. But those canines pack a chemical punch, helping the fang blenny escape the maw of would-be bullies.

Scientists and researchers from the University of Queensland in Australia have found the poison is "chemically unique".

Their behaviour is also intriguing, he said, for the way they appear unafraid of predators and fight for territory with similar-sized fish.

Prof Fry concluded: "This study is an excellent example of why we need to protect nature".
