Dear Colleagues,

Since we are on the topic, I thought I'd add that we also have a paper 
in press that addresses gene orders in the deep-sea octocoral families 
Paragorgiidae and Coralliidae, that includes data on variation levels of 
complete mitochondrial genomes  between 2 individuals of 1 species of 
Corallium (0.3%), as well as among species within each family.

The reference,
Figueroa, D.F., and A.R. Baco.  Complete mitochondrial genomes elucidate 
phylogenetic relationships of the deep-sea octocoral families 
Coralliidae and Paragorgiidae.  Deep-Sea Research II In press.

Best wishes,
