It took over 15 years and more than 1,000 remotely operated vehicle (ROV) expeditions, but researchers aboard the NOAA Ocean Exploration Trust's Nautilus finally spotted their research vessel's namesake in the wild. On December 3, operators of the ship's Hercules ROV located four specimens of Palau nautilus (Nautilus belauensis) during the Nautilus Exploration Program's ongoing, 17-day survey in the Palau National Marine Sanctuary. While the team recorded these particular examples swimming 220-to-375 meters (roughly 721-to-1,230 ft) below the Pacific Ocean's surface, the pelagic marine mollusk cephalopods can survive at depths approaching 2,500 feet. Their spiral-shelled bodies belong to one of Earth's oldest families of animals, with fossil records indicating the squid relatives have changed comparatively little even after nearly 500 million years. Although their sight is limited due to rudimentary eyes that lack solid lenses, nine known nautilus species instead rely heavily on their olfactory senses to find food and mates.

FRANKLIN the cuttlefish considered the juicy prawn meat morsel in front of her. As mouth-watering as it looked, she resisted temptation and waited for her favourite meal to become available – live shrimp. Her self-control is impressive and comparable to what we see in chimpanzees and crows. Self-control is a vital cognitive skill that underpins decision-making and future planning. In humans, these abilities are linked to sentience because they are thought to involve conscious experience.

This may seem obvious given my profession, but I think technology is...fine? It's hard to believe that it's safe for your kid to get anywhere near a Wi-Fi-enabled device when you read stories about tech addiction, hacked toys and horrible YouTube videos. It's also possible that my opinion might change as my kids get older. But I do believe it is possible for families to strike a balance between protecting their children and introducing them to the tools that they will be using for the rest of their lives. As a millennial, I've been on the Internet for as long as I can remember, but I've somehow grown to adulthood without marrying a talking toaster.

Squid and their cephalopod brethren have been the inspiration for many a science fiction creature. Their slippery appendages, huge proportions, and inking abilities can be downright shudder-inducing. But you should probably be more concerned by the cephalopod's huge brain--which not only helps it solve tricky puzzles, but also lets it converse in its own sign language. But it's not that: Certain kinds of squid send messages by manipulating the color of their skin. "Their body patterning is fantastic, fabulous," says Chuan-Chin Chiao, a neuroscientist at National Tsing Hua University in Taiwan.
