Now, new research shows that jellyfish are upending marine food webs—and disrupting ocean ecosystems' ability to sync carbon in the process.

Shape-Shifting Cuttlefish Can Mimic Pictures

Some cuttlefish can mimic the shape of objects around them for camouflage purposes. But recent research shows they can also mimic the shapes of two-dimensional photographs of objects! National Geographic has a photo gallery of cuttlefish doing their best to mimic their backgrounds, whether natural, plastic, 2D, or 3D.
