A lawsuit is in the works over the rare Clear Lake Hitch. The Center for Biological Diversity says it plans to sue the U.S. Fish and Wildlife Service for failure to put the tiny fish on the Endangered Species list. The center says that failure leaves the Hitch in what it calls–bureaucratic limbo–threatening a species that is vital to both the environment and to the culture of the Pomo tribe around the lake. A similar fish called the Clear Lake splittail already went extinct, and biologists are afraid that without emergency intervention, the Hitch will soon suffer the same fate. The lawsuit says the Trump administration has ignored the science and failed to finalize a rule that would list the fish as threatened with disappearing forever.
