The giraffe saw shovel is an insect in the family Scaridae, with a long upper jaw and serrated teeth. Giraffe saws and shovels live in Southeast Asia. The body length is 4-12 centimeters. It has the longest upper jaw and the sharpest serrations in the shovel armor. The end of the upper jaw has two forks, and the teeth on the left and right sides are asymmetrical and slightly curved. The protruding teeth on the upper jaw may appear aggressive, but in reality, the biting force is not strong. The tips of the teeth may appear sharp, but in reality, they are easily broken. There is also a glossy black shell. But the female insect does not have an upper jaw, while the young male insect likes to fight. The male insect's tooth roots are highly destructive and can cause certain injuries to various shovels.
