If the animal is endangered you still get dinged even of they are you pets. The laws are written as such to prevent this and things like getting an endangered or threatened species as a "pet" and then killing them to taxidermy.

No. It doesn't really matter if the animals are wild or in captivity.

Under the ESA, it is unlawful to "take" any endangered or threatened animal species, which is broadly defined to include harassing, harming, pursuing, hunting, shooting, wounding, or killing.

Its to discourage people from capturing wild endangered species and raising them as pets. Making something a pet is as good as killing it in the wild.

However, I don't think they're native to florida so I'm not sure it matters.
