The event celebrated at the Tropiquarium in Servion, Switzerland. The spokesperson for the facility: “A phenomenon that has never been observed before, neither in zoos nor in nature”
An extraordinary event. She was born – in captivity, at the Tropiquarium in Servion, Switzerland – the first giant tortoise of the Galápagos (Chelonoidis niger) albino (characterized by the total absence of pigmentation), as part of a conservation program for the endangered species. «We had the surprise of an albino puppy. A phenomenon never seen in the zoo and in natureThe spokesperson for the facility said. “We were surprised to discover a small albino among our baby giant tortoises” (here the story of “Fernanda”, the giant tortoise of the Galápagos believed extinct a century ago).
ALBINISM IN THE ANIMAL WORLD
Albinism is rare in turtles with about one case in 100,000 individuals, “compared to about one case in 20,000 individuals in humans”. In general, in the animal world, it also exposes those affected to various dangers: not only due to the extreme sensitivity of the skin, but also because it prevents camouflage and hiding from possible predators. The mother of the Swiss-born specimen, which weighs more than 100 kilograms, laid five eggs on February 11 last e the baby was born on May 1st. What has happened even more incredible is the extremely low mating success rate in this species: around 3%.
– Here is the Day of sea turtles which is celebrated on June 16.
DARWIN AT THE GALAPAGOS
The Galápagos Giant Tortoise (Chelonoidis niger) belongs to the Testudinidae family, endemic to the Pacific Ocean archipelago of the same name, famous (also) for the studies carried out by British naturalist Charles Darwin who arrived there on September 15, 1835. His journey – and the cataloging of over a hundred species – is recounted in The Voyage of the Beagle, published for the first time n
el 1839. The giant tortoises, which inhabit the Galápagos Islands, off the coast of Ecuador, are the largest living today: they can reach 300-320 kilograms in weight and even exceed 100 years of age. The species has differentiated in the different islands of the archipelago in thirteen subspecies (initially there were 15, but 2 have become extinct)
which are distinguished from each other by shape and size of the carapace (here the story of Diego and George, the two symbolic turtles of the island).
