A clade (or monophyletic group) is a group of species that includes an ancestral species and all of its descendants (i.e. members within the clade are all more closely related to each other than any members outside the clade).
What makes lightning make noise? Thunder is the sound that lightning makes. Sounds simple but why does lightning make a sound. Any sound you hear is made up of vibrations, the vibrations travel through the aiâ¦r as waves until they reach your ear.This means lightning must cause some vibrations.Lightning is a huge discharge of electricity.
Best Answer: Turtles do not HEAR- other than sensing vibration, so it only makes sense that they do not do much in the way of vocalizations. It does not help that they don't have vocal cords! However, they do make noises. During aggression, courtship, mating, egg-laying and similar situations, most turtles and tortoises make some sort of noise. The noises are basically a noisy breathing. They range from hisses and almost moaning, to a pig-like grunting, and even an almost chicken like 'cluck'.
