What may look like an organic organism is actually an image of a nuclear explosion photographed 1 millisecond after detonation. A rapatronic camera, which was used to capture the image above, is capable of an exposure time of 10 nanoseconds (which is equivalent to billionths of a second).

Nuclear explosion photographed by rapatronic camera less than 1 millisecond after detonation. From the Tumbler-Snapper test series in Nevada, 1952. The fireball is about 20 meters in diameter in this shot. The spikes at the bottom of the fireball are known as the rope trick effect. – Wikipedia
