A Shepard tone, named after Roger Shepard, is a sound consisting of a superposition of sine waves separated by octaves. When played with the bass pitch of the tone moving upward or downward, it is referred to as the Shepard scale. This creates the auditory illusion of a tone that continually ascends or descends in pitch, yet which ultimately seems to get no higher or lower.
Megamouth Shark
When scientists first discovered the megamouth shark in 1976 off the coast of Hawaii, it struck them as so bizarre that, to classify it, they created an entirely new genus and family.
Today, little is still known about the shark save for the fact that it has a large gaping mouth, which is indeed, very mega.
