Custom Taxonomy page not filtering by taxonomy

Hello,

I’ve created a custom post type ‘animals’ and one of the custom taxonomies is ‘animal-species’. The idea is that on the main animals page, that the user can filter them by species (so they would get a list of just cats or dogs, etc). Right now I have a lovely list of the species entered, however the taxonomy page for each doesn’t actually filter the animals by species, it shows all of them. I’ve created the file taxonomy-animal-species.php, but it doesn’t seem to be getting used. Most of my research in troubleshooting this problem is people getting a 404 error, but that’s not the case here. The custom taxonomy page just isn’t filtering the custom post types by the specified taxonomy.

TLDR: domain.com/animals/?animal-species=cat gives the same results as domain.com/animals/
