Interesting little video on the relationship between wolves and ravens, which scientists apparently still don’t really understand.
Classic animal motifs and pairings can be a powerful storytelling tool, if you know how to use them right. Wolves and ravens, for instance, match the archetypes of the strong, straightforward warrior or hunter and the quick-witted, cunning spy or thief, respectively; different approaches to problem solving that often complement one another (or, potentially, lead to interesting conflicts).
On the other hand, an ill-chosen animal motif can lead to the whole thing falling flat. Like, I remember hearing about one YA book where a leader character turned into a panda (I think). But a panda is not a good ‘leader’ animal; it’s a fat, lazy fuzzball that sits around eating bamboo. Pandas would work as ‘pudgy aristocrat’ or ‘pampered rich person’, but not as a commanding leader or warrior (Kung Fu Panda worked because Po starts out as a fat, completely unathletic nerd – a perfect ‘panda’ image who grows out of it through hard work).
Also make sure they fit the setting. I saw a trailer recently for a show called ‘Samurai Rabbit’, and while there were some things I liked about it, one thing that stood out as off is that one of the characters is a rhino. What is a rhino doing in a feudal-Japanese-style story? (There were rhinos in ancient China, but never in Japan to my knowledge).
Anyway, the point is that animal motifs are a subordinate art of their own; one worth taking the time to look into.
