The Melting Blobfish
The blobfish looks drastically different in its natural habitat than in the famous photos showing it as a sad, gelatinous blob. At depths of 3,000 feet, water pressure gives it a more normal fish shape. When brought to the surface, the pressure change causes its body to expand grotesquely. It hunts by simply floating slightly above the seafloor, waiting for edible particles to drift by.
