The people at the Texas Parks and Wildlife Department are concerned about this new Invasive Species of crawfish called the Australian Redclaw Crayfish that has started showing up across south Texas in the Rio Grand Valley. Crayfish, crawfish... same thing. I know the TP&W says that these are a dangerous and invasive species and all, but let's be real here, East Texas and Louisianna wants to know... are they good eatin'?
