1117: Octopuses Use Suckers To ‘Taste’ Harmful Microbes

Put on your party hat and wet suit because it is Cephalopod Week, Science Friday’s annual celebration of all things, octopuses, squid, and cuttlefish. To kick things off, we’re bringing you an ode to the octopus arm. You may have heard that octopuses can use their arms to “taste” their surroundings, which they use for finding food. Now, researchers have unlocked a key mechanism in the octopus sensory system. Octopuses use their suckers to detect harmful microbes on the surface of crab shells or even their own eggs.  Host Flora Lichtman talks with molecular biologist Nicholas Bellono about the latest in octopus sensory science. Guest: Dr. Nicholas Bellono is a professor of molecular and cellular biology at Harvard University.Transcripts for each episode are available within 1-3 days at sciencefriday.com.Subscribe to this podcast.
