This spring we encountered some striking greenish colored glass eels (see pictures in attach). So far, this pigmentation is restricted to the neck region (just behind the head) and a lateral area around the mandibular joints. Currently about 30 % of the population has this remarkable feature. It seems not to be related to feeding (both glass eels with or without food in the stomach) or pigmentation (so far encountered in VB - VIA2).
I haven't noticed this feature during my earlier investigations of glass eels in 2016 and 2017.
Any idea what this might represent or do you know someone who may know more about this?
Many thanks in advance!
cheers,
Jeroen
Dear Jeroen,
you could contact Eleonora Ciccotti from University of Rome 2. She has been working with eels for a long time, and she might help you

I would say this is quite common, you can see it one those numerous glass eels in the trapping ladder.
Thanks Cedric! Yep, it seems it is a rather common feature, although they seem not every year green like this...Great picture by the way.
Cheers!
