Abstract:
Healthy and sick crocodiles of varying sizes were examined from the Olifants River in the central part
of the Kruger National Park, the Sabi River in the southern part and the Shingwedzi River in the northern
region. Blood was collected for the determination of certain parameters and samples of fat, muscle,
kidney and liver tissue were collected and analyzed for their heavy metal content. The results of the
blood analyses are within the range recorded in the literature, but the metal analyses were inconclusive
as similar data are not available for comparison. The results of the metal analyses are presented
here for use as baseline and reference data.
