Erythrism or erythrochroism refers to an unusual reddish pigmentation of an animal's hair, skin, feathers, or eggshells. [1]
Causes of erythrism include:
Erythrism in katydids has been occasionally observed. The coloring might be a camouflage that helps some members of the species survive on red plants. [4] There is also consensus that the erythristic mutation is actually a dominant trait among katydid species, albeit a disadvantageous one, due to the overwhelmingly green coloration of most foliage. Hence, most pink or otherwise vividly colored katydids do not survive to adulthood, and this observation explains their rarity. [5] Erythrism in leopards is rare, but one study [6] reported that two of twenty-eight leopards seen in camera traps in a South African nature reserve were erythristic, and the authors found records of five other "strawberry" leopards from the region.

The blue crane, also known as the Stanley crane and the paradise crane, is the national bird of South Africa. The species is listed as Vulnerable by the IUCN.
Bees are winged insects closely related to wasps and ants, known for their roles in pollination and, in the case of the best-known bee species, the western honey bee, for producing honey. Bees are a monophyletic lineage within the superfamily Apoidea. They are currently considered a clade, called Anthophila. There are over 20,000 known species of bees in seven recognized biological families. Some species – including honey bees, bumblebees, and stingless bees – live socially in colonies while most species (>90%) – including mason bees, carpenter bees, leafcutter bees, and sweat bees – are solitary.
Insects in the family Tettigoniidae are commonly called katydids or bush crickets. They have previously been known as "long-horned grasshoppers". More than 8,000 species are known. Part of the suborder Ensifera, the Tettigoniidae are the only extant (living) family in the superfamily Tettigonioidea.
Orthoptera is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and weta. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts, and close relatives; and Ensifera – crickets and close relatives.
Guava is a common tropical fruit cultivated in many tropical and subtropical regions. The common guava Psidium guajava is a small tree in the myrtle family (Myrtaceae), native to Mexico, Central America, the Caribbean and northern South America. The name guava is also given to some other species in the genus Psidium such as strawberry guava and to the pineapple guava, Feijoa sellowiana. In 2019, 55 million tonnes of guavas were produced worldwide, led by India with 45% of the total. Botanically, guavas are berries.
Melanism is the congenital excess of melanin in an organism resulting in dark pigment.
Equine coat color genetics determine a horse's coat color. Many colors are possible, but all variations are produced by changes in only a few genes. Bay is the most common color of horse, followed by black and chestnut. A change at the agouti locus is capable of turning bay to black, while a mutation at the extension locus can turn bay or black to chestnut.
Leucism is a wide variety of conditions that result in partial loss of pigmentation in an animal—causing white, pale, or patchy coloration of the skin, hair, feathers, scales, or cuticles, but not the eyes. It is occasionally spelled leukism. Some genetic conditions that result in a "leucistic" appearance include piebaldism, Waardenburg syndrome, vitiligo, Chédiak–Higashi syndrome, flavism, isabellinism, xanthochromism, axanthism, amelanism, and melanophilin mutations. Pale patches of skin, feathers, or fur can also result from injury.
Leipzig Zoological Garden, or Leipzig Zoo is a zoo in Leipzig`s district Mitte, Germany. It was first opened on June 9, 1878. It was taken over by the city of Leipzig in 1920 after World War I and now covers about 27 hectares and contains approximately 850 species. By 2020 the zoo featured six different theme worlds, aiming at providing habitats appropriate for the species on display.
Fischer's lovebird is a small parrot species of the genus Agapornis. They were originally discovered in the late 19th century. They are named after German explorer Gustav Fischer.
A white horse is born predominantly white and stays white throughout its life. A white horse has mostly pink skin under its hair coat, and may have brown, blue, or hazel eyes. "True white" horses, especially those that carry one of the dominant white (W) genes, are rare. Most horses that are commonly referred to as "white" are actually "gray" horses whose hair coats are completely white. Gray horses may be born of any color and their hairs gradually turn white as time goes by and take on a white appearance. Nearly all gray horses have dark skin, except under any white markings present at birth. Skin color is the most common method for an observer to distinguish between mature white and gray horses.
Xeko is an out-of-print collectible card game revolving around endangered species. It was launched on Earthday 2006. It won the Creative Child Magazine 2006 Toy of the Year Award and the National Parenting Center's Seal of Approval in its first year. Four "Mission" sets have been released. Mission: Costa Rica and Mission: Madagascar, based on biodiversity hotspots were released first. Mission: Indonesia, was released in 2007, with the final release, Mission: China, was released July 19, 2008. A total of thirty more missions were planned but never developed.
Amelanism is a pigmentation abnormality characterized by the lack of pigments called melanins, commonly associated with a genetic loss of tyrosinase function. Amelanism can affect fish, amphibians, reptiles, birds, and mammals including humans. The appearance of an amelanistic animal depends on the remaining non-melanin pigments. The opposite of amelanism is melanism, a higher percentage of melanin.
Colours of the Syrian hamster can be described in three ways: as "self", "agouti" or "combinations". Self colours are a consistent coat colour with the same colour topcoat and undercoat. Agouti hamsters have a ticked coat, where each individual fur is banded in different colours. Agouti hamsters also have "agouti markings" which consist of dark cheek markings, a dark marking on the head, and a light underbelly. Combinations are produced when two self or agouti colours are present.
Durbanville Nature Reserve is a 6-hectare (15-acre) piece of protected land, located next to the Hollywoodbets Durbanville Racecourse in the Western Cape, South Africa.
The fauna of South Africa is diverse and largely typical of the ecosystems in Africa. South Africa is ranked sixth out of the world's 17 megadiverse countries. Many endemic species are unique to South Africa. The country is among the world leaders in conservation, but at the time wildlife is threatened by poaching and canned hunting.
Albinism is the congenital absence of melanin in an animal or plant resulting in white hair, feathers, scales and skin and reddish pink or blue eyes. Individuals with the condition are referred to as albinos.
Chortophaga viridifasciata, the green-striped grasshopper, is a species of band-winged grasshopper in the family Acrididae.
