1. Albinism
A rare genetic condition in which the body has no pigment whatsoever, due to an inherited inability to correctly manufacture melanin. This means that the animal with the condition (called an albino ) has white, pale pink, or even translucent skin, white fur or hair, and pink eyes (no pigment in the iris means that the only color comes from the blood vessels in the eye).

2. Albino
* An animal which has no pigment (melanin) whatsoever in its body. This means that its skin is white, pale pink, or even translucent, its fur (or hair) is white, and its eyes are pink (no pigment in the iris means that the only color comes from the blood vessels in the eye). * A plant which lacks part or all of its natural pigmentation or chlorophyll .

3. Industrial melanism
An increase in the amount of the pigment melanin in a population which lives in an area that has been darkened with pollution by human industrial activities. The extra melanin helps the individuals of the population to better camouflage themselves against predators in the darker surroundings. Industrial melanism occurs because lighter-colored individuals (ones without extra melanin) are found and eaten at a higher rate than darker-colored individuals.

4. Intermedin
A hormone secreted by the pituitary gland which stimulates the melanocyte s in the skin to make more of the pigment melanin .

5. Melanin
A pigment found in the skin, hair, and eyes of vertebrate animals. melanin protects the skin from damage by ultraviolet (UV) light and is the pigment which is produced in response to damage by the sun, causing skin to tan to protect against further damage. In vertebrate albino animals, melanin is the pigment which is missing from their bodies. The melanin molecule is formed when the amino acid tyrosine is oxidized.

6. Melanin
A pigment that gives the skin color and protects the underlying layers against damage by ultraviolet light; produced by melanocytes in the inner layer of the epidermis.

7. Melanism
An abnormally large amount of the pigment melanin in an organism, contributing to abnormally dark skin, hair and/or eyes. Melanism can be hereditary -- passed on from parent to offspring.

8. Melanocyte
A type of cell which is found in the epidermis of the skin and which produces the pigment melanin . Melanocytes are transparent cells with dendrite s.

9. Melanocytes
The cells in the inner layer of the epidermis that produce melanin.

10. Melanoma (melanocarcinoma, nevocarcinoma)
A type of skin cancer that develops from the dendritic clear cells in the epidermis (the melanocyte s) which produce melanin (skin pigment). There are three stages of melanoma: Stage I: The cancer is confined to the epidermis , Stage II: The cancer spreads through the epidermis and into the loose papillary dermis , Stage III: The cancer spreads through the papillary dermis
