Waters of the U.S.

West Liberty University Professor Zachary Loughman has dedicated his professional life to crustaceans – specifically freshwater crayfish. He dips his hand into one of the water tanks at his laboratory near Wheeling, West Virginia, to pick up a teal crayfish the size of a dollar bill.

“See the little guy dropping down? We caught mom and she had 300 babies. So we just let them grow,” Loughman said. “We’ve had our feet – my lab – in over 3000 rivers in the past ten years.”
