Researchers Capture Venomous Snake Strikes in High-Definition for First Time
For the first time, scientists have been able to capture venomous snake strikes in stunning high-definition, revealing three distinct ways these deadly predators take down their prey. The breakthrough came after a team of researchers traveled to Paris's Venomworld animal facility, where they crafted fake prey from medical gel and filmed 36 species of venomous snakes striking with multiple high-speed cameras.
The videos, which captured over 100 seconds of snake strikes, showed that most vipers strike within 0.1 seconds, outpacing even the fastest mammals' startle response. However, some elapids – a family of snakes including the rough-scaled death adder and the Cape coral snake – took longer to attack, with some species reaching their prey in over 0.3 seconds.
The researchers also observed different families of snakes injecting venom using distinct methods. Viperids struck quickly from a coiled position but sometimes didn't get an optimal bite angle, prompting them to pull out a fang and reinsert it before delivering the venom. Elapids, on the other hand, employed a sneaky approach by slithering up close to their prey before biting down multiple times, likely to prolong the venom flow.
Two species from the colubrid family – the mangrove snake and Fischer's tree snake – were also observed injecting venom through teeth at the back of their upper jaw. When the latter bit its fake prey, it dragged its fangs across the gel, creating crescent-shaped wounds that may help maximize venom delivery.
The researchers believe that future studies could explore whether the size of the prey affects the snakes' attack strategy. The detailed footage has provided a unique insight into the complex behavior of venomous snakes, shedding light on their hunting techniques and allowing for better understanding of these fascinating creatures.
