The albino fish have lower survival rates than normal fish but dress-out percentages are nearly equal.Some wild cave fish have populations that are albinistic. The Mexican cave tetra is a species that has evolved specialized characteristics in a series of independent caves. One of these is albinism linked to the Oca2 gene, a known pigmentation gene, This trait has evolved independently in at least two caves. In Chondrichthyes
In the class Chondrichthyes, several species of naturally occurring albino rays and sharks have been recorded. Furthermore, an albino individual spotted ratfish (Hydrolagus colliei) from the order Chimaeriformes has been reported.Albinistic individuals of the following shark species have been reported:
Basking shark (Cetorhinus maximus) – 2 cases
Broadnose sevengill shark (Notorynchus cepedianus)
Great white shark (Carcharodon carcharias)
Grey smooth-hound (Mustelus californicus) – 2 cases
Japanese topeshark (Hemitriakis japanica)
Japanese wobbegong (Orectolobus japonicus)
Java shark (Carcharhinus amboinensis)
Leopard shark (Triakis semifasciata)
Narrownose smooth-hound (Mustelus schmitti)
Pigeye shark (Carcharhinus amboinensis)
Porbeagle (Lamna nasus)
Scalloped hammerhead shark (Sphyrna lewini)
Spiny dogfish (Squalus acanthias)
Tawny nurse shark (Nebrius ferigineus)
Tiger shark (Galeocerdo cuvier) – embryo
Whale shark (Rhincodon typus)
Whitespotted bamboo shark (Chiloscyllium plagiosum)
Zebra shark (Stegostoma fasciatum)A study published in 2006 reported albinistic individuals of the following ray species:
Bat ray (Myliobatis californica)
Common skate (Raja batis)
Common stingray (Dasyatis pastinaca)
Common torpedo (Torpedo torpedo)
Cownose ray (Rhinoptera bonasus)
Giant electric ray (Narcine entemedor)
Giant oceanic manta ray (Manta birostris)
Ocellate spot skate (Okamejei kenojei)
Southern stingray (Dasyatis americana)
Thornback ray (Raja clavata)
Cuckoo ray (Raja naevus)

In Hyperoartia
There are several reports of albino lampreys and it has been estimated that this occurs at a frequency of one in 100,000 normal individuals.
Albinism has frequently occurred in progeny of Black Tartarian, Bing and Hedelfingen varieties of sweet cherry.Some herbicides (e.g. glyphosate and triazines) can cause partial chlorosis in plants, even several seasons or years after applicating. In human culture
The Albino Squirrel Preservation Society was founded at the University of Texas at Austin in 2001. Members of the society at the University of North Texas petitioned for an election to name their albino squirrel as the universitys secondary mascot. The University of Louisville in Kentucky also has a documented population of albino squirrels.Albino animals are often kept as pets, for example, African clawed frog, guinea pigs and peacocks.
