According to US researchers, sensors in the first layer of cells in the suction cups have adapted to react and detect molecules that do not dissolve well in water.
These sensors, called chemotactile receptors, use these molecules to help the animal find out what it is touching and whether that object is prey.
The chemotactile receptors send signals to the creatures nervous system…
