Most small, bottom-dwelling shark species are legal to own as a pet in the United States, and the sharks you can realistically keep number fewer than a dozen: brownbanded and whitespotted bamboo sharks, epaulette sharks, coral and marbled catsharks, horn sharks, and (at the upper limit) Japanese wobbegongs. No federal statute bans pet shark ownership outright. Three federal laws (the Endangered Species Act, CITES, and the Lacey Act) rule out protected species and illegally sourced animals, and state and local rules decide the rest.
Shark Species You Can Legally Keep
The sharks that work in private aquariums are small, slow, and spend most of their time resting on the substrate. Even the “small” ones reach two to four feet and live 20 to 25 years.
Brownbanded Bamboo Shark
The brownbanded bamboo shark (Chiloscyllium punctatum) is the species most commonly sold in the aquarium trade. Adults typically reach around 40 inches, with a maximum recorded length of about 52 inches.1FishBase. Chiloscyllium punctatum, Brownbanded Bambooshark Bamboo sharks of the genus Chiloscyllium have been known to live up to 25 years in captivity, and their eggs are widely available from breeders, so captive-bred animals are easy to source.
Whitespotted Bamboo Shark
The whitespotted bamboo shark (Chiloscyllium plagiosum) is one of the smaller options. Adults average 24 to 31 inches, with females reaching up to about 37 inches, and it is widely available as captive-bred eggs or juveniles.2Discover Fishes. Whitespotted Bambooshark
Epaulette Shark
The epaulette shark (Hemiscyllium ocellatum) reaches about one meter (roughly 39 inches) and lives 20 to 25 years. It can “walk” across the substrate using its pectoral and pelvic fins and tolerates low-oxygen conditions better than most sharks, which makes it somewhat hardier in a tank. Expect to pay significantly more than for a bamboo shark; prices often start around $1,000.
Coral and Marbled Catsharks
Coral catsharks (Atelomycterus marmoratus) stay around 24 to 28 inches, and marbled catsharks max out at roughly 24 inches. Their small adult size makes them the most manageable choice if tank footprint is your main constraint.
Horn Shark
The horn shark (Heterodontus francisci) can grow up to four feet and is one of the larger species kept by hobbyists.3Monterey Bay Aquarium. Horn Shark It is a cold-water species native to the eastern Pacific, so it needs cooler water than tropical bamboo sharks.
Japanese Wobbegong
The Japanese wobbegong (Orectolobus japonicus) can reach close to four feet and sits at the upper edge of what a dedicated hobbyist can realistically house, requiring a tank footprint of roughly eight feet by four feet.
Species You Cannot Keep
Several sharks that people ask about are either banned outright or carry trade restrictions that effectively put them out of reach of private owners.
The great white shark is a prohibited species in all U.S. waters and fisheries. No one can legally retain one under any circumstances.4NOAA Fisheries. White Shark: Management Under the Endangered Species Act, it is illegal to possess, sell, transport, or ship any species listed as endangered, and NOAA Fisheries extends similar protections to threatened species through special rules.5Office of the Law Revision Counsel. United States Code Title 16 Section 1538 The oceanic whitetip shark was proposed for full ESA Section 9 protections as a threatened species, which would prohibit possession and commercial activity involving it.6Federal Register. Protective Regulations for the Oceanic Whitetip Shark Scalloped hammerheads carry ESA protections internationally.
CITES Appendix II covers a long list of sharks: all requiem sharks (the entire family Carcharhinidae, added in November 2023), makos, threshers, hammerheads, silky sharks, porbeagles, whale sharks, basking sharks, and great whites.7U.S. Fish & Wildlife Service. CITES Export Permit and Introduction From the Sea Application Form Guidance for U.S. Shark Fishers and Dealers An Appendix II listing is not a ban, but anyone importing or exporting those species must obtain CITES permits proving legal acquisition and non-detriment to the species. Commercial importers and exporters also need an Import/Export License from the U.S. Fish and Wildlife Service’s Office of Law Enforcement, which carries a $100 application fee.8U.S. Fish & Wildlife Service. Frequently Asked Questions Concerning Certificates Needed for CITES-Listed Sharks and Rays
Beyond legal protections, size rules out most other species. Nurse sharks reach 14 feet despite their reputation as gentle. Blacktip reef sharks and every species of hammerhead are off the table for home aquariums. Sharks that grow beyond four feet, swim pelagically, or carry federal protections should not be in a private tank.
For the home aquarist, the practical upshot is this: the species most commonly sold as pets (bamboo sharks, epaulette sharks, catsharks) are not currently CITES-listed, so domestic purchases from captive breeders involve no CITES paperwork. If a species is on the list, or you’re importing from overseas, the permit requirements apply to you.
State and Local Rules
Federal law sets the floor. Your state may go much further.
A handful of states explicitly ban private possession of sharks. Arizona classifies sharks as restricted live wildlife. Nevada prohibits possession of sharks alongside piranhas and stingrays. Other states take a permit-based approach, requiring an exotic animal or restricted species permit before you can legally keep a shark at home. Permit fees vary widely: some states charge under $100 annually, others charge several hundred dollars and may require a facility inspection before approval.
Many states have no specific shark ownership law at all, instead deferring to federal protections or regulating sharks only in a fishing context. Even where state law is silent, your city or county may have its own exotic animal ordinance, and homeowners’ associations can add another layer. Before committing to a purchase, check with your state’s fish and wildlife agency and your local animal control office. Getting caught without a required permit risks confiscation and fines, and you won’t be able to rehome a confiscated shark on your own terms.
How to Buy a Shark Without Breaking Federal Law
The Lacey Act is the law most private owners stumble into. It makes it a federal crime to import, export, sell, acquire, or transport any fish or wildlife taken in violation of any U.S., tribal, state, or foreign law.9U.S. Fish & Wildlife Service. Lacey Act Buying a shark that was illegally collected, or one that crossed state lines in violation of another state’s law, exposes you to prosecution. Felony violations carry fines up to $20,000 and up to five years in prison. Misdemeanor violations can mean up to $10,000 and a year behind bars. You are effectively responsible for knowing whether your shark was legally obtained.
That makes the sourcing decision a legal one, not just an ethical one. Captive-bred sharks from reputable breeders and licensed dealers come with documentation of the animal’s origin and any required CITES paperwork for listed species.7U.S. Fish & Wildlife Service. CITES Export Permit and Introduction From the Sea Application Form Guidance for U.S. Shark Fishers and Dealers A good dealer will ask about your tank setup before completing a sale, and some refuse to sell if the home isn’t adequate. Avoid anonymous online sellers who can’t verify the animal’s origin. A wild-caught shark sold without documentation could have been taken illegally, and buying it exposes you to Lacey Act liability regardless of what you knew.9U.S. Fish & Wildlife Service. Lacey Act
Shipping Rules
If you buy from an out-of-state breeder, the shark will need to be shipped, and live animal shipping has its own rules. International shipments of CITES-listed species must pass through a designated U.S. port, and the receiving Wildlife Inspection Office must be notified at least 48 hours before arrival. All international wildlife shipments require a Declaration for Importation or Exportation of Fish or Wildlife.8U.S. Fish & Wildlife Service. Frequently Asked Questions Concerning Certificates Needed for CITES-Listed Sharks and Rays Failure to comply can result in seizure and enforcement action. Domestic shipments of non-CITES species face fewer federal hurdles, but you still need to comply with any state import permits.
What Legal Ownership Actually Requires
“Legal” is not the same as “practical.” Even when every permit is in order, a pet shark is a decades-long commitment that costs far more than most buyers expect.
For a brownbanded bamboo shark, expect to need at least 360 gallons for an adult. Epaulette sharks are similar. Catsharks can sometimes get by in 180 to 200 gallons. Horn sharks and Japanese wobbegongs push the requirement past 500 gallons. A 300-gallon acrylic aquarium setup (tank, stand, canopy) runs roughly $3,900 to $6,200 from specialty retailers. A commercial protein skimmer adds $800 to $1,600. Add a sump, return pump, heater, powerheads, lighting, salt, substrate, and test kits, and total equipment costs run $7,000 to $12,000 before the shark.
The shark itself is often the cheapest part. A whitespotted bamboo shark from a reputable dealer starts around $100. An epaulette shark starts around $1,000.
Monthly operating costs are real too. Electricity for 24-hour heaters, pumps, and skimmers can add $100 to $170 per month. Sea salt for water changes runs $40 to $50 monthly. Food costs vary: a couple of coral catsharks might eat $20 of seafood a month, a larger bamboo shark with tankmates could run $90 or more. Realistic monthly operating costs fall between $200 and $400 for a single-shark setup.
Veterinary care is scarce and expensive. Exotic aquatic vet visits typically start around $235 per appointment, and not every city has a qualified practitioner. A serious illness can easily cost $500 to $1,000 in diagnostics and treatment if you can find a vet who handles elasmobranchs. There is no “shark insurance” comparable to pet insurance for dogs and cats.
One more structural note that catches owners off guard: a 300-gallon aquarium filled with water weighs approximately 2,500 pounds from the water alone, and the full setup can reach 3,000 pounds or more sitting on a few square feet of floor. Most residential wood-framed floors are built to handle 40 pounds per square foot, so tanks over 125 gallons generally need structural reinforcement unless they sit on a concrete slab at ground level. A structural engineer consultation is a worthwhile expense before you commit to placement.
If You Can No Longer Keep Your Shark
Sharks outlive the commitment of many owners. A bamboo shark bought as a six-inch hatchling will still be alive and demanding hundreds of dollars a month in care 20 years later. How you handle an exit matters legally.
Some public aquariums accept donated sharks, but entirely at their discretion, based on exhibit space, the animal’s health, and the fit with their collection. Donations are unconditional, and no aquarium will accept a shark that wasn’t legally obtained.10Aquarium of the Pacific. Contact the Aquarium Call well in advance and be prepared for a no. Rehoming through hobbyist forums and local marine aquarium societies is another option; verify that the recipient’s setup is adequate and that the transfer complies with any state transport permits.
Do not release a pet shark into the ocean, a lake, or any other body of water. Releasing non-native aquatic species is illegal under multiple federal and state laws. Violations of the injurious wildlife provisions of the Lacey Act alone can result in up to six months in jail and fines of $5,000 for individuals or $10,000 for organizations.11U.S. Department of the Interior. Injurious Wildlife Exclusion Released sharks also face near-certain death from temperature shock or environmental incompatibility, and surviving animals can harm local ecosystems.
