First record of the invasive Australian redclaw crayfish <i>Cherax quadricarinatus</i> (von Martens, 1868) in the Crocodile River, Kruger National Park, South Africa
The redclaw crayfish Cherax quadricarinatus (von Martens, 1868), a robust freshwater crayfish native to Australia and Papua New Guinea, has now been recorded from the Kruger National Park (KNP). Previously absent from the Crocodile River, SAN Parks received a report in February 2016 of redclaw crayf...
