    Molecular Secrets of Cephalopod Skin
    Cephalopods—a class of marine animals that includes squids, octopuses and cuttlefish—can readily change the appearance of their skin to blend into their surroundings or mimic other species. These stunning camouflage abilities come from optical components in the skin, such as light-reflecting cells and pigmented organs, along with an underlying musculature that alters the skin’s texture and shape.

    MBL Virtual Programs
    These free events are part of the MVP (MBL Virtual Programs) webinar series. This virtual series ran from July 6-17 and included offerings from many of our summer programs including the advanced research training courses and the Logan Science Journalism program. We are very excited to reconnect with our friends and colleagues, learn from distinguished speakers, and engage in lively scientific discussion. Webinars were recorded and are available for viewing via the links below.

    Octopuses taste their food when they touch it with their arms

    Octopuses can taste their prey before eating it by using their arms to “lick” it, which researchers say adds to evidence that the cephalopods’ eight appendages are analogous to tongues with “hands” and “brains”.

    How Octopuses Use Their Suction Cups to Taste Through Touch
    A new study reveals that the invertebrates use a novel kind of receptor embedded in their suckers to explore their ocean habitats.

    How octopuses taste their meals by touching them, according to a new study
    "A lot of people say an octopus is like an alien," says filmmaker Craig Foster in his new Netflix documentary "My Octopus Teacher."
    "But the strange thing is, as you get closer to them you realize that you're very similar in a lot of ways."

    When It Comes to Octopuses, Taste Is for Suckers

    Touch and taste? It’s all in the suckers
    Octopuses have captured the human imagination for centuries, inspiring sagas of sea monsters from Scandinavian kraken legends to TV’s “Voyage to the Bottom of the Sea” and, most recently, Netflix’s less-threatening “My Octopus Teacher.” With their eight suction-cup covered arms, their very appearance is unique, and their ability to use those appendages to touch and taste while foraging further sets them apart.

    Molecular Basis of Chemotactile Sensation in Octopus
    • The distributed octopus arm nervous system uses unique chemotactile receptors (CRs)
    • CRs detect poorly soluble natural products mediating touch-taste arm behavior
    • CRs form ion channel complexes to mediate diverse signal detection and filtering
    • Signals transduced by specific sensory cells regulate complex exploratory behavior
