Florida Prohibited Nonnative Species: Penalties and Amnesty

Florida’s prohibited nonnative species list, maintained by the Fish and Wildlife Conservation Commission under Florida Administrative Code Chapter 68-5, bans personal possession of dozens of animals whose invasive potential threatens the state’s ecosystems, agriculture, or public safety.¹ The list includes large constrictor snakes, tegus, green iguanas, Nile monitors, several venomous marine species, most tilapia, and a handful of mammals including mongooses and giant pouched rats. Keeping one without a qualifying permit or grandfather status is a first-degree misdemeanor punishable by up to a year in jail and a $1,000 fine, and federal law can pile on top of that.

What “Prohibited” Means in Florida

Florida sorts nonnative wildlife into three tiers, and the label matters because it decides both what you’re allowed to do and how hard the state comes down if you get it wrong. Prohibited species sit at the top: you cannot possess one as a pet, breed it, sell it, import it, or release it. The only lawful holders are researchers, educational exhibitors, and specific authorized commercial operations, all of whom need FWC permits and must meet strict containment standards.²

Conditional species are a step down. They still require permits and biosecurity measures, but a wider range of entities can hold them, including qualifying commercial breeders and aquaculture operations.³ Non-regulated species fall outside both categories and can generally be possessed without special authorization. Penalties for prohibited-species violations run significantly steeper than for conditional-species violations, so the tier a species falls into is the first thing to check.

Prohibited Reptiles

Reptiles dominate the list. Florida’s subtropical climate lets tropical reptiles breed year-round, and once a population takes hold in the Everglades or surrounding wetlands, eradication is essentially impossible.

Large Constrictor Snakes

The Burmese python is the most notorious entry. These snakes have devastated small mammal populations across the Everglades, preying on raccoons, bobcats, and marsh rabbits so effectively that some species have nearly vanished from areas with established python populations.⁴ The full prohibited-snake roster includes:

Indian and Burmese python (Python molurus)
Reticulated python (Python reticulatus)
Northern African python (Python sebae)
Southern African python (Python natalensis)
Amethystine python (Morelia amethistinus)
Scrub python (Morelia kinghorni)
Green anaconda (Eunectes murinus)
Yellow anaconda (Eunectes notaeus)
Beni anaconda (Eunectes beniensis)
DeSchauensee’s anaconda (Eunectes deschauenseei)
Brown tree snake (Boiga irregularis)

Every species on this list shares traits that make it dangerous once loose: they grow large, breed prolifically, and face few or no natural predators here. The brown tree snake isn’t a large constrictor on the same scale, but it wiped out most native bird species on Guam and is prohibited here to prevent a repeat.⁴

Lizards and Monitors

Green iguanas, all tegu species in the genera Salvator and Tupinambis, and Nile monitors are prohibited. Argentine black and white tegus raid the nests of ground-nesting birds and gopher tortoises. Green iguanas cause property damage by burrowing into seawalls and canal banks. Nile monitors are aggressive predators that compete with native wildlife across a range of habitats.⁴

Sea Snakes

All species in the family Hydrophiidae are prohibited, with a narrow exception described in the administrative code.⁴

Prohibited Mammals

The mammal list is shorter but targets species with serious disease or ecological risks:

Gambian and Emin’s giant pouched rats (Cricetomys species), which can carry monkeypox and grow large enough to compete aggressively with native wildlife
Flying foxes (genus Pteropus), large fruit bats that can damage orchards and carry pathogens
Mongooses and meerkats, notorious for decimating native bird and reptile populations on islands where they’ve been introduced
Dholes (genus Cuon), pack-hunting wild dogs
Brushtail possums (Trichosurus vulpecula), an invasive marsupial that damages vegetation and competes with native mammals

One point of confusion worth clearing up: nutria, the large invasive rodent that plagues other Gulf Coast states, does not appear on Florida’s current prohibited list.⁴

Prohibited Aquatic Species

The prohibited marine species are weever fishes (family Trachinidae), stonefishes (genus Synanceia), and sea snakes, all of which deliver dangerous or potentially lethal venom.⁴

In fresh water, the most notable entries are walking catfishes (family Clariidae, except the common walking catfish Clarias batrachus, which is conditional rather than prohibited) and most tilapia species in the genera Tilapia, Sarotherodon, Alcolapia, and Oreochromis. A handful of commercially important tilapia species are excluded from the ban, including blue tilapia (O. aureus) and Nile tilapia (O. niloticus).⁴ The common walking catfish’s conditional status means it can be kept with a permit under biosecurity requirements; the rest of its family cannot be kept at all.³

Lionfish Are Handled Separately

Lionfish are a major invasive threat to Florida reefs, but they aren’t on the standard prohibited list. They fall under their own rule, 68-5.009, which bans importing live lionfish and breeding them in captivity while actively encouraging people to harvest wild lionfish from Florida waters.⁵ FWC wants lionfish removed from the ocean, not just kept out of pet stores.

Penalties for Possessing a Prohibited Species

Possessing, importing, or releasing a prohibited species is a Level Three violation under Florida law, which is a first-degree misdemeanor punishable by up to one year in jail and a fine of up to $1,000.⁶⁷

Penalties escalate for repeat offenders. A second Level Three violation within ten years carries a mandatory minimum fine of $750 and permanent revocation of all wildlife licenses and permits. Another violation after that revocation reaches Level Four, a third-degree felony.⁶

Violations involving venomous nonnative reptiles, such as releasing a venomous species or selling one illegally, start at Level Four with no prior conviction needed. By contrast, violations involving conditional species (the less-restricted category) are Level Two, a second-degree misdemeanor carrying up to 60 days in jail and a $500 fine.⁸⁹

If You Already Own One

Not everyone with one of these animals is automatically breaking the law. Florida carved out grandfathering provisions when species were added to the list, though most windows have closed.

For large constrictors (Burmese pythons, reticulated pythons, Northern and Southern African pythons, amethystine pythons, scrub pythons, and green anacondas) and Nile monitors, anyone who held a valid reptile of concern license and possessed the animal for personal use before July 1, 2010, may keep it for the animal’s natural life. The owner has to maintain a valid reptile of concern license under Section 379.372, Florida Statutes.⁴

Green iguanas and tegus followed a different path. When these species moved to the prohibited list more recently, existing pet owners had to microchip their animals, register them with FWC, and obtain a no-cost permit by the compliance deadline. Owners who completed that process can keep their pets. Those who missed the deadline are technically in violation.²

The Exotic Pet Amnesty Program

If you’re past the grandfathering window and have a prohibited species without a permit, the Exotic Pet Amnesty Program is the safer path. The program lets owners surrender nonnative animals and receive temporary amnesty from Chapter 68-5, so you don’t face penalties for the possession itself during the surrender process.¹⁰

You start with an online rehoming form through FWC. The commission places surrendered animals with permitted adopters and even books and pays for the animal’s flight following international cargo guidelines, though you’re responsible for preparing a flight container and getting the animal to the nearest cargo hub.¹⁰ Adopters who accept prohibited snakes or lizards must complete an inventory form and submit it to FWC within 72 hours, and all adoptions must be reported to and approved by the program before the animals change hands.¹¹ The program does not accept dogs, cats, rabbits, guinea pigs, livestock, or native Florida species.

Permits for Research, Exhibition, and Commercial Use

Outside of grandfathered pet ownership, possessing a prohibited species requires an FWC permit. Eligible purposes include scientific research, educational exhibition, and eradication or control efforts. Green iguanas and tegus can also be possessed for qualifying commercial sales, though that exception is narrow and closely regulated.²

Applications require detailed biographical information, documented experience with the species, and a containment plan meeting Chapter 68-5 standards, including sketches or photos showing the enclosure can withstand storms and floods and a Critical Incident Disaster Plan describing what happens if an animal escapes.¹² You must have the physical permit in hand before acquiring or transporting any prohibited species. Moving the animal first and hoping the permit comes through later is a criminal offense.

Federal Penalties Under the Lacey Act

Florida’s list doesn’t stand alone. The federal Lacey Act maintains its own “injurious wildlife” list that overlaps with Florida’s prohibitions. Burmese pythons, Northern African pythons, green anacondas, and walking catfish appear on both. Bighead carp and silver carp, while not on Florida’s state prohibited list, are federally classified as injurious and cannot be imported into the country or transported across state lines.¹³

Federal penalties run independently of state charges, so the same act can trigger both. Under the Lacey Act, knowingly importing or trafficking injurious wildlife with a market value exceeding $350 carries up to five years in federal prison and a $20,000 fine. Even a lower-level “should have known” violation can mean up to one year in prison and a $10,000 fine.¹⁴

Anyone transporting injurious wildlife across state lines for research or education must obtain a separate federal permit (Form 3-200-42) from the U.S. Fish and Wildlife Service on top of any Florida permit. Federal applications require double escape-proof enclosures and copies of state authorization, with processing times running up to 40 weeks when a facility inspection is needed.¹⁵
