Some (small) additional links, found with a custom search engine. Javascript-heavy sites are currently unfindable. I can crawl from a given start point, if there are zoos who know additional sites.
- Zoo writers guild: https://zoowg.org/index.php
- Forum ZOOne (German only): https://www.forumzoone.org/
- Animal Zoo France (French): https://www.animalzoofrance.com/
- Zoo’d (band, sadly only one song for now): https://soundcloud.com/user-359230302
- Unverifiable (spotted April 2, has since gone down): https://zooey.cat
- Currently down (archive site): https://zdu.se
These were found from a crawl using the resources listed at https://zoopride.net/#resources – A good site for things that are still around.
