One of 4 species of glass frog spotted in Yatama reserve. We spotted this species a couple of times. Since it was night, it was tough to get a habitat shot but this was on a rock beside a small stream.

Blue-green pigment in the bones of the garfish (Belone belone) and eelpout (Zoarces viviparus).
I know other glass frogs also have green bones but I wasn't aware of any other animals or amphibians.
I am reading up more and more on green bones and the other species that have them. Fascinating.
I'm glad you researched it Sukanya because I had no idea! Thanks and thanks ornithoptera!
It seems that the green bone colouration is caused by an accumulation of a metabolic byproduct called biliverdin, a green bile pigment. (But why bile pigment should land up in the bone still eludes me.) Anyway, learnt something FANTASTIC today. Thank you Natgeo, dandoucette and PN.
Wow, great shot
So cute! Green bones!!! How?? So interesting.
