Researchers Turn Squid Suckers Into New Material Some suckers on the arms of Humboldt squid, which are much larger than the bigfin reef squid seen here, are ringed with sharp teeth that share some special properties with spider silk. When the 100-pound Humboldt squid wraps its tentacles around its prey, the sharp teeth studding some of its suckers dig in and hold on. They’re remarkable tools made from tough and flexible proteins called suckerins that are the same family as the keratin in our fingernails—but may be even more useful.

Article:               Octopi Have a Brain in Every Tentacle Print Slowly, humans have been finding out that the animals around us are a lot smarter than we thought. The lowly octopus is kind of like an animal genius. Octopi share a common ancestor with humans from 750 million years back: a worm with eye spots. But, while humans keep the brain in one spot, octopi do not. They only have about 500 million neurons, which is 1/20th of what our brains have. The brain of an octopus works like an internet of brains! Their main CPU is only the size of a walnut, but each of their 8 arms carry packets of neurons too.
