What is that thing that classifies different species, it’s called a daxatonomy or something? It’s like:
Step1: Dog has curly tail?
Yes) See step 2
No) See step 3
Step2: Dog has point ears?
Yes) Shiba Inu
No) See step 4
And it goes on? Does anybody know what it is?
Not to be confused with taxidermy. 
which is where stuffed animals come from
