What’s interesting about the Water Treader?

  • Water Treaders either walk or run on the water surface.

  • They detect their prey from vibrations of the water surface.


  • Like the Water Strider, the legs of the Water Treader have fine, feathery, water repellent hairs on their feet, which allow them to stand on the water surface.
