Prosopocoilus giraffa, the giraffe stag beetle, is the world's largest stag beetle[1] and is a member of the family Lucanidae within the order Coleoptera.

They have very long, toothed and notched mandibles that protrude about half the size of their body.

Males fight each other using these strong and enlarged jaws to lift and throw rivals to win a mate.

Several distinctive populations (subspecies) are found in moist forested region areas of Asia, ranging from India to Indonesia.
