The world's only albino giraffe born in a Tennessee zoo

An albino giraffe, described as unique in the world, was born at Brights Zoo in Limestone, in the American state of Tennessee. The event is extraordinary because it is the first documented giraffe specimen with a complete absence of pigmentation, an extremely rare genetic condition in this species.

The animal, a male, was born last month and was presented to the public only recently after an observation period. The zoo's veterinarians confirmed that the calf, despite its extremely rare condition, is in good health and is being closely monitored.

The birth has attracted the attention of biologists and wildlife enthusiasts from around the world, highlighting how such events are exceptional cases that contribute to the understanding of genetic variants in captive animal populations.

Albinism is a congenital genetic condition characterized by the complete or partial absence of melanin pigmentation in the skin, hair, and eyes. It is caused by an inherited alteration in melanin metabolism. In wild animals, this condition is rare because the responsible genes are recessive and must be inherited from both parents.

In giraffes, sightings of individuals with color variations, such as the white giraffe reported in Kenya in 2017, have already been documented, but these were cases of leucism, a different condition that causes a partial loss of pigmentation. A case of true complete albinism, with red eyes and a total absence of pigment, had never been officially recorded in the species.

Birth in a zoo, where conditions are controlled and genealogy is often tracked, allows for better study of these rare occurrences. The survival of an albino animal in the wild is often difficult due to increased visibility to predators and sensitivity to sunlight. In a controlled environment, however, it can live a full life, even becoming an ambassador for species conservation and genetic research.
