T- or T represents difference appearances of the enzyme Tyrosinase. From Wikipedia, Tyrosinase also known as monophenol monooxygenase is an enzyme that catalyses the oxidation of phenols (such as tyrosine) and is widespread in plants and animals. Tyrosinase is a copper-containing enzyme present in plant and animal tissues that catalyzes the production of melanin and other pigments from tyrosine by oxidation, as in the blackening of a peeled or sliced potato exposed to air. It is found inside melanosomes.

This enzyme's character in the two appearances alters the black/melanin to result in either animals with no black-only white in the T- or animals with a lavendar-off white in the T . Both appearances are striking to say the least in teh adult appearance when you see the full maturity of hte body colors.

I don't have a T- but here is an older pic of my T . The orange is now vibrant deep red.
