👉 The rat's weapon, known as the incisor, is a specialized, sharp-edged tooth found on the front of its jaw. Rats use this incisor to gnaw through various materials, including wood, paper, and even human-made objects like wires and packaging. This unique adaptation allows them to create sharp edges for digging burrows, opening containers, and maintaining their dental health by continuously gnawing. The incisor is also crucial for self-defense, enabling rats to bite off portions of their fur or skin when threatened.
