Corydalus cornutus

Habitat

Weird but real

Males grow 4cm curved mandibles they literally can't bite with. They are purely for showing off to females and wrestling other males.

Why it's cool

Like a tiny dragon designed by someone who wanted maximum drama with zero practical engineering. The tusks are pure performance art.
