If you went to NYTimes.com Monday afternoon, you were treated to a side by side looping, animated images at the top of its homepage. The images embedded are in an .mp4 video file but it looked lik e an animated Gif.

It featured a jellyfish known as Phacellophora camtschatica. To the right appears a rotating glass model of another jellyfish species, Cotylorhiza borbonica, frequently found in the Mediterranean. They appear above the headline of a story, "In Pursuit of an Underwater Menagerie,". It is about a filmmaker's quest to document the rare underwater invertebrates.
