8,000 Miles from Home: Australian Redclaw Crayfish Discovered in Texas Waters

Biologists have discovered an invasive species in Texas waters: the Australian red claw crayfish. This freshwater crustacean, originally from Australia and Papua New Guine,a is located in the Rio Grande Valley. These crayfish can reach lengths of up to 9.8 inches, competing with lobsters in size.

The species probably arrived here through aquarium dumping, a practice in which pet owners release non-native animals into the wild. According to Texasinvasives.org, this practice has the potential to introduce disease and disrupt ecosystems.

The warm climate of South Texas is akin to that of Australia’s Northern Territory, enabling the crayfish to thrive and possibly expand its range. “The potential impact on native fish and crayfish species remains uncertain,” stated Archis Grubh, an invertebrate biologist with the Texas Parks and Wildlife Department.

Researchers strive to manage the species to prevent damage to local fish populations and plant life. Conservationists call on the public to refrain from releasing aquarium pets into natural waterways.
