The comb jelly—also known as the warty comb jelly, sea walnut, or Mnemiopsis leidyi—has a disappearing butt. Sidney Tamm of the Marine Biological Laboratory in Woods Hole, Massachusetts, told New Scientist that "there is no documentation of a transient anus in any other animals that I know of. It is not visible when the animal is not pooping. There's no trace under the microscope. It's invisible to me."
If a storm is passing and the sun starts shining, you might be lucky enough to spot a rainbow. But did you know that you can see something just as amazing at night? While they're incredibly unusual, moonbows (or lunar rainbows) are caused by the reflection, refraction, and dispersion of light, and tend to happen most often in places with waterfalls and mist. There also needs to be a near full moon for there to be enough light for you to see it.
