Cape Hare
The Cape hare (''Lepus capensis''), also called the brown hare and the desert hare, is a hare native to Africa and Arabia extending into India. Taxonomy The Cape hare was one of the many Mammalia in the 10th edition of Systema Naturae, mammal species originally described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae, 10th edition of ''Systema Naturae'', where it was given the binomial name of ''Lepus capensis''. The taxon is part of a species complex. ''Lepus tolai'' and ''Lepus tibetanus'' were moved out based on geographic distribution and molecular characteristics. The current remaining grouping of ''Lepus capensis sensu lato'' remains paraphyletic. Description The Cape hare is a typical hare, with well-developed legs for leaping and running, and large eyes and ears to look for threats from its environment. Usually, a white ring surrounds the eye. It has a fine, soft coat which varies in colour from light brown to reddish to sandy grey. Unusually amo ...

Ancient Egyptian Hieroglyphs
Ancient Egyptian hieroglyphs ( ) were the formal writing system used in Ancient Egypt for writing the Egyptian language. Hieroglyphs combined Ideogram, ideographic, logographic, syllabic and alphabetic elements, with more than 1,000 distinct characters.In total, there were about 1,000 graphemes in use during the Old Kingdom period; this number decreased to 750–850 during the Middle Kingdom, but rose instead to around 5,000 signs during the Ptolemaic period. Antonio Loprieno, ''Ancient Egyptian: A Linguistic Introduction'' (Cambridge: Cambridge UP, 1995), p. 12. Cursive hieroglyphs were used for Ancient Egyptian literature, religious literature on papyrus and wood. The later hieratic and demotic (Egyptian), demotic Egyptian scripts were derived from hieroglyphic writing, as was the Proto-Sinaitic script that later evolved into the Phoenician alphabet. Egyptian hieroglyphs are the ultimate ancestor of the Phoenician alphabet, the first widely adopted phonetic writing system. Moreov ...

Semi-desert
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSh'' and ''BSk'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as they usually cannot support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): * mu ...

Precocial
Precocial species in birds and mammals are those in which the young are relatively mature and mobile from the moment of birth or hatching. They are normally nidifugous, meaning that they leave the nest shortly after birth or hatching. Altricial species are those in which the young are underdeveloped at the time of birth, but with the aid of their parents mature after birth. These categories form a continuum, without distinct gaps between them. In fish, this often refers to the presence or absence of a stomach: precocial larvae have one at the onset of first feeding whereas altricial fish do not. Depending on the species, the larvae may develop a functional stomach during metamorphosis (gastric) or remain stomachless (agastric). Precociality Precocial young have open eyes, hair or down, large brains, and are immediately mobile and somewhat able to flee from or defend themselves against predators. For example, with ground-nesting birds such as ducks or turkey (bird), turkeys, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-backed Jackal
The black-backed jackal (''Lupulella mesomelas'') is a medium-sized Caninae, canine native to East Africa, eastern and southern Africa. These regions are separated by roughly . One region includes the southernmost tip of the continent, including South Africa, Namibia, Botswana and Zimbabwe. The other area is along the eastern coastline, including Kenya, Somalia, Djibouti, Eritrea, and Ethiopia. It is listed on the IUCN Red List as least concern due to its widespread range and adaptability, although it is still persecuted as a livestock predator and rabies Vector (epidemiology), vector. Compared to members of the genus ''Canis'', the black-backed jackal is a very ancient species, and has changed little since the Pleistocene, being the most Basal (phylogenetics), basal wolf-like canine. It has a reddish brown to tan coat and a black saddle that extends from the shoulders to the base of the tail. It is a Monogamy in animals, monogamous animal, whose young may remain with the family ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caracal
The caracal (''Caracal caracal'') () is a medium-sized Felidae, wild cat native to Africa, the Middle East, Central Asia, and arid areas of Pakistan and northwestern India. It is characterised by a robust build, long legs, a short face, long tufted ears, relatively short tail, and long canine teeth. Its coat is uniformly reddish tan or sandy, while the ventral parts are lighter with small reddish markings. It reaches at the shoulder and weighs . It was first scientific description, scientifically described by German naturalist Johann Christian Daniel von Schreber in 1776. Three subspecies are recognised. Typically nocturnality, nocturnal, the caracal is highly secretive and difficult to observe. It is territory (animal), territorial, and lives mainly alone or in pairs. The caracal is a carnivore that typically preys upon birds, rodents, and other small mammals. It can leap higher than and catch birds in midair. It stalks its prey until it is within of it, after which it ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leopard
The leopard (''Panthera pardus'') is one of the five extant cat species in the genus ''Panthera''. It has a pale yellowish to dark golden fur with dark spots grouped in rosettes. Its body is slender and muscular reaching a length of with a long tail and a shoulder height of . Males typically weigh , and females . The leopard was first described in 1758, and several subspecies were proposed in the 19th and 20th centuries. Today, eight subspecies are recognised in its wide range in Africa and Asia. It initially evolved in Africa during the Early Pleistocene, before migrating into Eurasia around the Early–Middle Pleistocene transition. Leopards were formerly present across Europe, but became extinct in the region at around the end of the Late Pleistocene-early Holocene. The leopard is adapted to a variety of habitats ranging from rainforest to steppe, including arid and montane areas. It is an opportunistic predator, hunting mostly ungulates and primates. It relies on it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ambush Predator
Ambush predators or sit-and-wait predators are carnivorous animals that capture their prey via stealth, luring or by (typically instinctive) strategies utilizing an element of surprise. Unlike pursuit predators, who chase to capture prey using sheer speed or endurance, ambush predators avoid fatigue by staying in concealment, waiting patiently for the prey to get near, before launching a sudden overwhelming attack that quickly incapacitates and captures the prey. The ambush is often opportunistic, and may be set by hiding in a burrow, by camouflage, by aggressive mimicry, or by the use of a trap (e.g. a web). The predator then uses a combination of senses to detect and assess the prey, and to time the strike. Nocturnal ambush predators such as cats and snakes have vertical slit pupils helping them to judge the distance to prey in dim light. Different ambush predators use a variety of means to capture their prey, from the long sticky tongues of chameleons to the expand ...

Cheetah
The cheetah (''Acinonyx jubatus'') is a large Felidae, cat and the Fastest animals, fastest land animal. It has a tawny to creamy white or pale buff fur that is marked with evenly spaced, solid black spots. The head is small and rounded, with a short snout and black tear-like facial streaks. It reaches at the shoulder, and the head-and-body length is between . Adults weigh between . The cheetah is capable of running at ; it has evolved specialized adaptations for speed, including a light build, long thin legs and a long tail. The cheetah was first Species description, described in the late 18th century. Four subspecies are recognised today that are native to Africa and central Iran. An African subspecies was Cheetah reintroduction in India, introduced to India in 2022. It is now distributed mainly in small, fragmented populations in northwestern, East Africa, eastern and southern Africa and central Iran. It lives in a variety of habitats such as savannahs in the Serengeti, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coprophagy
Coprophagia ( ) or coprophagy ( ) is the consumption of feces. The word is derived from the Ancient Greek "feces" and "to eat". Coprophagy refers to many kinds of feces-eating, including eating feces of other species (heterospecifics), of other individuals (allocoprophagy), or one's own (autocoprophagy). Feces may be already deposited or taken directly from the anus. Some animal species eat feces as a normal behavior, whereas other species may eat feces under certain conditions. Coprophagia by plants Some carnivorous plants, such as pitcher plants of the genus '' Nepenthes'', obtain nutrition from the feces of commensal animals. Notable examples include '' Nepenthes jamban'', whose specific name is the Indonesian word for toilet. Manure is organic matter, mostly animal feces, that is used as organic fertilizer for plants in agriculture. Coprophagia by nonhuman animals By invertebrates Coprophagous insects consume and redigest the feces of large animals. These fec ...

Herbivore
A herbivore is an animal anatomically and physiologically evolved to feed on plants, especially upon vascular tissues such as foliage, fruits or seeds, as the main component of its diet. These more broadly also encompass animals that eat non-vascular autotrophs such as mosses, algae and lichens, but do not include those feeding on decomposed plant matters (i.e. detritivores) or macrofungi (i.e. fungivores). As a result of their plant-based diet, herbivorous animals typically have mouth structures ( jaws or mouthparts) well adapted to mechanically break down plant materials, and their digestive systems have special enzymes (e.g. amylase and cellulase) to digest polysaccharides. Grazing herbivores such as horses and cattles have wide flat- crowned teeth that are better adapted for grinding grass, tree bark and other tougher lignin-containing materials, and many of them evolved rumination or cecotropic behaviors to better extract nutrients from plants.

Nocturnal
Nocturnality is a ethology, behavior in some non-human animals characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnality, diurnal meaning the opposite. Nocturnal creatures generally have highly developed senses of hearing (sense), hearing, olfaction, smell, and specially adapted eyesight. Some animals, such as ferrets, have eyes that can adapt to both low-level and bright day levels of illumination (see metaturnal). Others, such as bushbaby, bushbabies and (some) bats, can function only at night. Many nocturnal creatures including tarsier, tarsiers and some owl, owls have large eyes in comparison with their body size to compensate for the lower light levels at night. More specifically, they have been found to have a larger cornea relative to their eye size than diurnal creatures to increase their : in the low-light conditions. Nocturnality helps wasps, such as ''Apoica flavissima'', avoid hunting in intens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
