Claim: this is a photo of Spanish Dancer Jellyfish

Other captions used:

• Spanish dancer sea slug
• Deep sea jellyfish

The claim is false. The image is computer generated fractal artwork by Francis Le Guen. The artwork is based on a photo of Spanish dancer, which is not a jellyfish. The image was created with fractal flame editor called Apophysis. You can find this and other fractal artwork from Le Guen’s blog (in French).
