I found this pretty fascinating. It is the stinger of a bee, taken with an electromagnetic scanning system. The red color of the stinger is not correct for that reason.
But if you look close, the stinger is split in two separate halves, barbs are on the side. When the bee stings you, the stinger slides side to side to get deeper into your skin. Fascinating, but also painful.
