Strid

Strid is a term used in biology to describe a specialized breathing opening or pore found in certain amphibians, insects, and some other animals. It functions as part of their respiratory system, allowing them to directly exchange gases—such as oxygen and carbon dioxide—with their environment. In frogs, for example, the strid is an opening on the side of the body that helps facilitate breathing, especially when the animal is underwater or in low-oxygen conditions. Essentially, it’s a biological structure that enhances respiratory efficiency, enabling these animals to survive and function effectively in their habitats.
