Cephalopod Passes Cognitive Test Designed For Human Children

mi shares a report from ScienceAlert: The marshmallow test, or Stanford marshmallow experiment, is pretty straightforward. A child is placed in a room with a marshmallow. They are told, if they can manage not to eat the marshmallow for 15 minutes, they’ll get a second marshmallow, and be allowed to eat both. This ability to delay gratification demonstrates cognitive abilities such…

The First Gene-Edited Squid in History Is a Biological Breakthrough

Squid are among the smartest ocean dwellers. Along with other ink-squirting cephalopods like octopuses and cuttlefish, squid boast the largest brains of all invertebrates. They also have an incredibly complex nervous system capable of instantaneously camouflaging their bodies and communicating with each other using various signals. From a report: Scientists have long marveled at these sophisticated behaviors and have tried to…

Scientists Give Cuttlefish 3D Glasses To Prove They Perceive Depth

New submitter wolff000 writes: A group of researchers at the University of Minnesota have shown that cuttlefish see in 3D. They did this by making 3D glasses and then showing the cuttlefish movies of prey. “While cuttlefish wearing glasses is an unexpected sight, a University of Minnesota-led research team built an underwater theater and equipped the cephalopods with specialized 3D glasses…

Cuttlefish wearing 3D glasses prove they sense depth just like us

Cuttlefish eyes move independently, making it difficult to compare images from each eye and sense depth. Surprisingly, they still sense distance the same way we do Source: https://www.newscientist.com/article/2229477-cuttlefish-wearing-3d-glasses-prove-they-sense-depth-just-like-us/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
