A tiny fish could hold the key to future developments for painkillers.
The fang blenny, which has two large canine teeth jutting out of its lower jaw, uses its venom to put off potential attackers.
Researches have discovered that the venom for the Blenny is in fact painless, following tests on lab mice.
When a larger fish attempts to eat a blenny, the tiny fish bites the predator’s gums, resulting in the predator’s blood pressure falling, loss of coordination before finally opening its mouth, permitting the blenny to escape.
According to scientists, the venom is unique. The Blenny is commonly found around Australia’s Great Barrier Reef.
If the venom can be adapted, it could be a major breakthrough in pain relief.
