Which animal species that hasn't been introduced to California accidentally or intentionally (yet) would become invasive if brought there?

In case you thought there's no wild boars, carp, or starlings in California yet, you can look it up here:


No, fictional animals do not count, since they never existed in real life. I meant real life modern animals that don't exist in California's wilderness/cities yet.

    Probably plenty of different birds.

    Alligators, although they may not count since they've been brought before, but not released into the wild in colony numbers.  Same for snapping turtles and several other turtle species.  (Red-eared sliders are here already.)

    A few Australian crayfish.

    A lot of Australian spiders.

    A few Hawaiian fruit flies.

      Alligators do count because they're not breeding in California (yet).

    Here's the animals that may potentially invade the cities/wilderness of California if introduced to California:

    *Flying foxes

    *Any species of non-human primate

    *Nine-banded armadillos

    *Crested porcupines (aka Old World porcupines)

    *Prairie dogs

    *Any species of mongooses

    *Raccoon dogs




    *Common cuckoos




    *Alligator snapping turtles

      That is not a real animal, that's a fictional alien from Star Trek franchise. I'm asking what real life Earth animal would become invasive if it were introduced to California (the animals that aren't found in California yet).
