Video: Ergens zit een groot dier verstopt, zie jij hem?

Je ziet het dier in dit filmpje niet. Pas als de duiker te dichtbij komt, laat hij zich zien.

      Jagers moeten intelligent zijn. Maar idd, wat dit beestje allemaal kan met z’n velletje en voortbeweging.
      Had ik een zwembad , kocht ik er enkele.

          autiluses are much closer to the first cephalopods that appeared about 500 million years ago than the early modern cephalopods that appeared maybe 100 million years later (ammonoids and coleoids). They have a seemingly simple brain, not the large complex brains of octopus, cuttlefish and squid, and had long been assumed to lack intelligence. But the cephalopod nervous system is quite different from that of other animals, and recent experiments have shown not only memory, but a changing response to the same event over time.[16][17][18]

          In a study in 2008, a group of nautiluses (N. pompilius) were given food as a bright blue light flashed until they began to associate the light with food, extending their tentacles every time the blue light was flashed. The blue light was again flashed without the food 3 minutes, 30 minutes, 1 hour, 6 hours, 12 hours, and 24 hours later. The nautiluses continued to respond excitedly to the blue light for up to 30 minutes after the experiment. An hour later they showed no reaction to the blue light. However, between 6 and 12 hours after the training, they again responded to the blue light, but more tentatively. The researchers concluded that nautiluses had memory capabilities similar to the “short-term” and “long-term memories” of the more advanced cephalopods, despite having different brain structures.[16][17][18] However the long-term memory capability of nautiluses was much shorter than that of other cephalopods. The nautiluses completely forgot the earlier training 24 hours later, in contrast to octopuses, for example, which can remember conditioning for weeks afterwards. However, this may simply be the result of the conditioning procedure being suboptimal for sustaining long-term memories in nautiluses.

            wat mooi om te weten, dank voor de informatie. Op de site van de octopus ( groot dier verstopt ) staat ook een 50 minuten film over the Volcano octopus.
