Japanese eel, Anguilla japonica. Showing fluorescent colours when photographed under special blue or ultraviolet light and filter. Its muscle fibres produce the first fluorescent protein identified in a vertebrate. It's totally different” from other fluorescent proteins. For example, instead of producing light with a chromophore that is part of the protein sequence, as the classical Green Fluorescent Protein (GFP) does, UnaG fluoresces when it binds a naturally occurring small molecule called bilirubin, a breakdown product of haemoglobin used in hospital tests for decades to assess liver function and diagnose diseases such as jaundice.
