However, the albino strain shows more solitarious behaviour.The yellow mutation in fruit flies is a mutation causing a congenital lack of normal pigment; it is a similar phenomenon to albinism in other organisms. In echinoderms
The Japanese sea cucumber (Apostichopus japonicus) is an echinoderm that is caught in the wild or cultivated for food. Normal Japanese sea cucumbers start to develop pigmentation when they are about 1 cm long. The upperside becomes a dull, yellowish -brown to maroon and the underside a light brown. The body walls of adult, albino Japanese sea cucumbers contain only 0.24% melanin compared to 3.12% in normal adults. The difference in melanin content becomes visually apparent at 60 days of age. The epidermis is thinner in the albinos and contains fewer melanocytes. Albino individuals are similar to normal individuals in growth rate, digestion rate and fertility.Astaxanthin is the main carotenoid in marine crustaceans (and fish). It has been shown that adding astaxanthin to the feed can improve the skin and muscle colour of marine organisms and thereby increase their commercial and ornamental value. In arachnids
"Depigmented" arthropods have been found, usually in cave populations. "Albino" individuals of normally red citrus red mites (Panonychus citri) occasionally appear in laboratory colonies, however, these still contain green and yellow pigments. This albinism does not affect mortality. Related pigment disorders
In some animals, albinism-like conditions may affect other pigments or pigment-production mechanisms:

"Whiteface," a condition that affects some parrot species, is caused by a lack of psittacins.
Screening
Metabolic disorder screening can be done in newborns via blood, skin, or hearing tests. Management
Metabolic disorders can be treatable by nutrition management, especially if detected early. It is important for dieticians to have knowledge of the genotype to create a treatment that will be more effective for the individual. See also
