Vector generated image of Cape porcupine(Hystrix africaeaustralis):Habitat: Porcupines are found in woodland, savannah and forest biomes as well as rocky outcrops. Behaviour: They often take shelter in aardvark (Antbear) burrows which they modify to make more comfortable. The porcupine is...

Painting of House Mouse (Mus musculus):It is a small mammal and a rodent.House mice usually walk, run or stand on all fours, but when eating, fighting or orienting themselves, they stand only on the hind legs, supported by the tail. When running, the horizontal tail serves for balance; the end...

Painting of Black wildebeest (Connochaetes gnou):East-central South Africa, mainly eastern northern Cape and Free State: formerly central Cape Province to Natal and southern Transvaal.Open plains, formerly in Karoo (arid shrublands) and grassland.Primarily a grazer, preferring short grasses; in...

Painting of Eastern rock sengi (Elephantulus myurus):distributed across southern Africa from western Mozambique in the north to Orange Free State in the south, and in southern Zimbabwe, eastern Botswana, and throughout the Transvaal.live in the semi-arid, temperate savannas of southern Africa,...

Painting of Gansu pika (Ochotona cansus):are endemic to China and are located in the Ganzu, Qinghai, and Sichuan provinces.inhabit alpine shrub habitats, which are part of steppe-meadow environments. Ganzu pikas live in alpine areas where temperatures fall below freezing even during summer...

Painting of Jentink’s duiker (Cephalophus jentinki) DISTRIBUTION Found in western Guinea, HABITAT Fragmented habitats, consisting of fruiting trees and thick canopies. A group is said to be living in the forests outside of Freetown, Sierra leone.Relies primarily on the tree seedlings, fruits,...

Painting of Matamata (Chelus fimbriatus), DISTRIBUTION :Northern South America, including the Amazon and Orinoco Rivers. HABITAT This highly aquatic freshwater species prefers the still waters of oxbow lakes and ponds. Anecdotal evidence suggests that this species survives...

Painting of Spotted harlequin snake (Homoroselaps lacteus), Diet: The Spotted Harlequin Snake, also known as the spotted dwarf garter snake, is nocturnal and given to prowling in and out of grass tufts, where its favourite prey, legless lizards of genus Scelotes, reside. It also preys on small...

Vector generated image of Gas Syringe: A gas syringe also known as glass collecting bottle, is a piece of laboratory glassware used to insert or withdraw a volume of a gas from a closed system, or to measure the volume of gas evolved from a chemical reaction. A gas syringe can also be used to...

Vector generated image of Bar Magnet: Each end of a bar magnet is considered a pole – one being north, the other south. When freely suspended, a bar magnet will align itself so that the end of its northern pole points towards the Earth’s magnetic North Pole. This works in the exact same...

Vector generated image of Pendulum:A pendulum is a weight suspended from a pivot so it can swing freely.When a pendulum is displaced from its resting equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When...
