In deeper waters it has been found that these pigments can fluoresce UV-A and violet light into more photosynthetically useable light.
Mike most of that is associated with the presence of UV's. at deeper levels. Here is the general concept. Thier about 3 major protien based pigments that are know. each absorbs light at a particluar range of wave length, in turn they fluoresce at a slightly higher wave length, were talking 10 to 30 MN, so not a sweeping change, but enough to add to the total of the light. Again how this all looks to the human eye is a completely different subject.

Thanks for the point in the right direction. Just did a little reading...
Looked at some layman information on flavines, urobilines and pterines. Hopefully not outdated, most info dated around 1999.
Also I think I need to read some more about mycosporine-like amino acids (MAAs).
Anyways a green flourecening pigment can be activated by 380nm light and the energy that flouresces back is somewhere from 450-530nm. Aparently the reason many corals become flourescent green the the aquaria under strong lights according again to Borneman.
As a side note, anyone know of any lights that primarily peak at 650-700nm??? I think I have an at home experiment I want to setup...
I gotta go do some more reading...
