Churchill once said that Russia's policy was like "a riddle wrapped in a mystery inside an enigma". Since MagpieGoose solved the last quiz so easily, I have followed Churchill's formula in this one.
First you have to solve the enigma by identifying the 10 species shown above (there is no need to worry about subspecies). Then there is the mystery of finding the links between them. Finally you have to solve the riddle and explain how you reached your answer.
After Kakapo's comment last time, I have taken care to make this puzzle fairer. If your English is good enough to read and understand this question, it is more than good enough to find the answer; although everyone will need some knowledge of other areas to make progress.
I'm not going to give any hints yet, but I will confirm the identities of the species involved as they emerge.
Have fun!
