evidence: One example of a gecko species with venomous saliva is the Gekko vittatus, also known as the Yemen black-eyed gecko. Found in the Arabian Peninsula and parts of Africa, this species possesses specialized glands in its lower jaw that produce a toxic substance. When threatened, it can deliver venomous bites to its prey or potential predators, injecting them with a potent cocktail of toxins. While the venom's effects on humans have not been extensively studied, it is known to cause pain, swelling, and tissue damage in affected animals. [...] In conclusion, while there are a few gecko species that possess venomous saliva or produce toxins, the danger they pose to humans is relatively low. Most geckos are harmless and play a beneficial role in their ecosystems by controlling insect populations. As with any encounter with wildlife, it is important to exercise caution and respect their space to avoid any potential harm. [...] No, geckos do not have venom. Unlike some other reptiles, such as snakes or lizards, geckos do not possess venom glands or venomous fangs. They rely on their agility, camouflage, and ability to shed their tails for defense, rather than venomous bites or stings.
