Multiple hearts for a wyvern is strange considering invertebrates have multiple hearts where as vertebrates usually have 1 heart consisting of a variety of chambers as in chambers where blood vessels connect. There is only one explanation for this as (previously mentioned) must mean a different planet and another possible point for the hole setting to be in a different planet.

Also about for your previous DYN, it's kinda shocking that the female does the fighting in air yet real-life lions also have similar society as you see males slacking while females doing hunting, now I am not saying that teostra is lazy as I would be insulting one of my favourite monsters in the whole series nor am I saying they are more related to our lions than the wyverns , however , I am stating is that Teostra weighs more and is less agile than lunastra. Sorry for being AFF (Away From the Forum).

PS - My lunastra and teostra claim was here due to free space and another favourable sun and moon duo
