I personally suspect it’s not common in the animal kingdom. It’s quite likely a defense against leprosy, a disease that is most dangerous in larger society type communities, without outside predators (to pick off the sick).
That theory might be wrong however. Its distribution would tell us a lot about what it defends against.


















This idea was tried previously. If done right, it doesn’t take much energy to damage a mosquito’s wings.
Secondly, a laser is only a real issue for vision if the eye focuses on it. With a continuous beam, it would be instinctive, making it dangerous. If the pulse is short enough however, the eye won’t have time to focus and so the power will be safely spread out, even inside the eyeball.
