Pale Fox
The pale fox (''Vulpes pallida'') is a species of fox found in the band of African Sahel from Senegal in the west to Sudan in the east. It is one of the least studied of all canid species, in part due to its remote habitat and its sandy coat that blends in well with the desert-like terrain. The pale fox is distinguished by its light-colored fur and oversized ears, which enable it to excel in camouflage and survival in harsh environments. Individuals of the species serve as key predators and scavengers. Despite being lesser known, the pale fox is considered a significant indicator of an ecosystem's health and a focal point for conservation interests. Subspecies There are five recognized subspecies: * ''Vulpes pallida pallida'' * ''Vulpes pallida cyrenaica'' * ''Vulpes pallida edwardsi'' * ''Vulpes pallida harterti'' * ''Vulpes pallida oertzeni'' Description The pale fox is a small fox, with a long body and relatively short legs and a narrow muzzle. The fur is quite thin, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tail
The tail is the elongated section at the rear end of a bilaterian animal's body; in general, the term refers to a distinct, flexible appendage extending backwards from the midline of the torso. In vertebrate animals that evolution, evolved to lose their tails (e.g. frogs and hominid primates), the coccyx is the homologous vestigial of the tail. While tails are primarily considered a feature of vertebrates, some invertebrates such as scorpions and springtails, as well as snails and slugs, have tail-like appendages that are also referred to as tails. Tail-shaped objects are sometimes referred to as "caudate" (e.g. lobes of liver#Caudate lobe, caudate lobe, caudate nucleus), and the body part associated with or proximal to the tail are given the adjective "caudal (anatomical term), caudal" (which is considered a more precise anatomical terminology). Function Animal tails are used in a variety of ways. They provide a source of thrust for aquatic locomotion for fish, cetaceans and cr ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. Four savanna forms exist; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests.Manoel Cláudio da ...
