Florida now has a new, non-reptilian invasive species: Capybaras. Capybaras could become Florida's next invasive species - Orlando Sentinel
actually the article specifically says the capybara is not yet an invasive species, it simply has a small population in the wild in Florida. The article from which that article was based (here: https://www.sciencenews.org/blog/wi...y-be-poised-be-florida’s-next-invasive-rodent) goes into a bit more detail, and also says that it is only suspected rather than proven that the capybara are an established population. They compare capybara to coypu, which are invasive - however the two species have completely different habits and I don't think any comparison is apt.
They have been feral in Florida for at least 20 years. Was told once that they were probably escapes from Lubee back when they had more than just bats.
