...blood? I am intrested in the biology of cold blooded animals. Is there a rna transcription in the blood of cold blooded species?

Absolutely, all eukaryotes have the same RNA transcription mechanism.

However, red blood cells of animals do not contain nuclei and so do not contain DNA or RNA.

What do you mean by an RNA marker in their blood (free RNA)? Free RNA doesn't last a millisecond outside of a cell due to the presence of nucleases, unless its encapsulated in a virus capsid.

Could you rephrase the question...are you looking to see if there is a unique type of RNA expressed by cold blooded animals only? I'm not sure I understand what you are looking for.
