The Australian redclaw crayfish, an invasive species native to northern Australia and Papua New Guinea, has been spotted in Southern Texas, raising concerns among environmental officials about its potential threat to local wildlife and ecosystems. First reported in the U.S. in 2013, the crayfish have been sighted in the Rio Grande Valley, prompting an investigation by Texas Parks and Wildlife Department. Researchers are studying the extent of their spread and potential impact, with concerns about their rapid reproduction rate and ability to outcompete native species. The crayfish, while not harmful to humans, can carry a parasite that affects native crayfish species. The species is edible and commercially farmed in Australia, but it is unlikely that there are enough in Texas waters for consumption. The introduction of the crayfish in the U.S. is believed to be a result of “aquarium dumping,” where well-meaning aquarium owners release their pets into the wild. Officials urge anyone who spots the crayfish to report it to Texas Parks and Wildlife to help track and monitor their presence in the region.
