Homo Ebony and Tov Homo Ebony
Extra dark or "Homo" Ebony chinchilla. Ebony is not known to exist in a true homozygous state so the term can be misleading.
A pure black ebony will still throw a standard baby. I use the term homo becuase it is easier to type than extra dark.
2011 - Nice young Homo Ebony female in bright sunlight.
2011 - Sister to the girl above that is not quite pure black but very close.
2012 - Another young female.
Tov Homo Ebony Male from 2004.
It is difficult to tell if a pure black chinchilla is Tov. Some times the fur texture is a little different but often you have to wait until they throw a Tov baby.
