Kruger National Park, South Africa

Thirty-three species of amphibians are found in the Park, as well as 50 fish species. A Zambesi shark, Carcharhinus leucas, also known as the bull shark, was caught at the confluence of the Limpopo and Luvuvhu Rivers in July 1950. Zambezi sharks tolerate fresh water and can travel far up rivers like the Limpopo.
Anti-poaching measures
The park's anti-poaching unit consists of 650 SANParks game rangers, assisted by the SAPS and the SANDF (including the SAAF). As of 2013, the park is equipped with two drones borrowed from Denel and two Aérospatiale Gazelle helicopters, donated by the RAF to augment its air space presence. Automated movement sensors relay intrusions along the Mozambique border to a control center, and a specialist dog unit has been introduced. Buffer zones have been established along the border with Mozambique, from where many poachers have infiltrated the park, as an alternative to costly new fences. The original 150 km long fences were dropped in 2002 to establish the Great Limpopo Transfrontier Park. The national anti-poaching committee oversees all activities and coordinates interested parties.
