Need a generic Animal tag [Risolto]

I think that a generic tag

Animal

is needed, to be able to tag any kind of coins with animals

There was recently the exact opposite request here,
https://en.numista.com/forum/topic73085.html

to have more unique tags.

We need both generic animal and specific animals, otherwise we are going to have a huge lists of tag (yesterday I was cataloguing coins with antelopes and cocodriles), and it would be very nice to have tags organized by specialization, that it is if you had horse automatically you add also Animal

In my original idea there was a more hierarchical structure (multilevel), where we can tag something as animal (if no more specific tag is available), as a bird (if not recognisable or very specific) or as an eagle. Then when you search for bird you get both those with a bird tag and those with an eagle/penguin/owl/.... tag. Now you have to select all birds or mammals separately if you want to get them all.
