There are several genetically different lineages of Pontoscolex corethrurus, some of which may be separate species. This is a problem we are also studying. When we observe that "P. corethrurus" is found in widely varying conditions, including extreme, we cannot yet be sure that we are talking about the same "species" of worm. So it is possible that the populations you have in India are the same as the Azores populations, or not. Only detailed examination and DNA data can tell for sure.

It is Avelona ligra, from France, in the Lumbricidae. we have not obtained D. longa yet. There are many others. Eisenia lucens for example- but most of these secrete a body fluid that luminesces when expelled. Avelona glows blue all the time.

We have a constitutively bioluminescent worm's transcriptome. If you have a bioluminescent worm handy, I am sure we can do more. A colleague of mine is really keen to get others.
