"Venomous" refers to organisms that produce venom, a toxic substance used for defense or to subdue prey. This venom is typically delivered through specialized structures, such as fangs in snakes or stingers in scorpions. Venom can cause a range of effects, from pain and swelling to more severe reactions, depending on the species and the amount injected. Many animals are classified as venomous, including spiders, jellyfish, and certain fish. Venomous creatures play important roles in their ecosystems, helping to control populations of other animals and serving as a food source for predators. Understanding venomous species is crucial for safety and biodiversity conservation.
