Knocking sand frog, Sandveld pyxie, Kruger burrowing frog
The knocking sand frog (Tomopterna krugerensis ), also known as sandveld pyxie or Kruger burrowing frog, is a species of frog in the family Pyxicephalidae. It is found in southern Angola, Namibia, Botswana, southern Zimbabwe, southern Mozambique, northern South Africa, and Eswatini. This species was discovered during the evening of 23 October 1973 in South Africa's Kruger National Park. Two weeks after heavy rain fell in the area, large numbers were found around the Machayi and Mathlakuza Pans in the northeastern part of the Park near the Mozambican frontier.

starts withMales measure 38–45 mm (1.5–1.8 in) and females 41–46 mm (1.6–1.8 in) in snout–vent length. It is a stout frog with short, broad head. The fore limbs are also short and stout, whereas the hind limbs are longer than body when extended. Fingers have no webbing whereas the toes have some webbing. The tympanum is present but can be indistinct. The dorsum is typically cream-beige, but may vary from very pale grey-brown to a mid-brown. There are many irregular, khaki-brown markings, outlined with dark-brown to black. There are also bright orange tubercles scattered over entire dorsum, each with a black rim. The venter is immaculate white.
Tomopterna krugerensis is not morphologically distinguishable from Tomopterna cryptotis and Tomopterna tandyi, but the male advertisement call is distinct: a slowly repetitive, percussive "knock" or "cluck", almost like a metronome.
