Fish venom found to be painless but can disorient attackers
Researchers at Liverpool, UK, studying a two-inch-long blenny fish found its venom components to induce no pain when injected into lab mice. Researchers believe the venom might cause a sudden drop in blood pressure leaving the attacker disoriented and unable to chase. Researchers also found that the fangs (teeth) of the fang blenny fish evolved before the venom, unlike snakes.
