  Shark’s only smooth from front to back. Otherwise shark’s sandpaper.

    Nope. Sharks are smooth as hell in all directions.

      In general, the crowns of dermal denticles have cusps pointing tailward, which is why a shark feels relatively smooth if stroked from head-to-tail but sandpapery coarse if stroked the other way.

        It’s telling me that shark skin is “smooth from all directions and at all times”

  I still remember when I went to an aquarium as a kid and touched the sting rays. That texture has stayed in my mind ever since. I still can’t find anything it compares well to.
