Shipping live animals, such as reptiles, amphibians, fish, and invertebrates, can pose challenges at any time of year.
Shipping live animals, such as reptiles, amphibians, fish, and invertebrates, can pose challenges at any time of year. We often hear concerns about shipping animals during the cold of winter, but summer heat also presents challenges that need special attention. These creatures are sensitive to temperature fluctuations, so ensuring their safety during transit requires careful planning.

Here are some general guidelines we have compiled to help transport these animals safely. Safe shipping temperature guidelines must be met at the shipping origin, along with the shipping destination, as well as in any major shipping hubs likely to handle your shipment. These guidelines can also be helpful when transporting a new animal home.
1. Temperature Requirements
Research the optimal temperature range for the animals you are shipping and ensure that these conditions can be maintained throughout the journey. There are specific temperature requirements for certain species, and failing to meet these standards can lead to problems. Adhere to the correct temperature protocols for the animal you intend to ship.
Here are some generalized recommendations for temperature guidelines when shipping different animals:
Amphibians:
Below 38°F: Do not ship. Wait for warmer weather.
38°F to 59°F: Use a heat pack.
60°F to 79°F: Do not use a heat pack.
80°F to 92°F: Use a cold pack.
92°F to 100°F: Ship to a “FedEx Ship Center” facility only.
Over 95°F: Do not ship. Wait for cooler weather.
Reptiles:
Below 38°F: Do not ship. Wait for warmer weather.
38°F to 69°F: Use a heat pack that lasts at least 40 hours.
70°F to 91°F: Do not use a heat pack.
92°F to 100°F: Ship to a “FedEx Ship Center” facility only.
Over 95°F: Do not ship. Wait for cooler weather.
Invertebrates: (terrestrial/arboreal):
Below 38°F: Do not ship, wait for warmer weather.
38°F to 65°F: Use a heat pack.
66°F to 91°F: Do not use a heat pack.
92°F to 100°F: Ship to a “FedEx Ship Center” facility only.
Over 100°F: Do not ship. Wait for cooler weather.
Tropical Fish/Corals:
Below 40°F: Do not ship, wait for warmer weather.
40°F to 69°F: Use a heat pack.
70°F to 79°F: Do not use a heat pack.
80°F to 89°F: Use a cold pack.
90°F to 95°F: Ship to a “FedEx Ship Center” facility only.
Over 95°F: Do not ship. Wait for cooler weather.
Axolotls/Cold Water Fish:
Below 30°F: Do not ship, wait for warmer weather.
30°F to 49°F: Use a heat pack.
50°F to 69°F: Do not use a heat pack or a cold pack.
70°F to 79°F: Use a cold pack.
80°F to 85°F: Ship to a “FedEx Ship Center” facility only.
Over 85°F: Do not ship. Wait for cooler weather.

2. Insulation
Insulation is crucial for protecting animals from dangerous temperature fluctuations. Use insulated shipping boxes with foam inserts to maintain a stable internal temperature. Line the inside of the box with a thermal barrier, such as several sheets of newspaper or similar padding, to provide extra insulation. Proper substrate, moisture sources, or even hygroscopic materials may need to be supplied to keep excess moisture at bay for some animals.
3. Adding Warmth
Heat packs are essential for keeping the shipping container warm. Choose heat packs that last between 40 and 72 hours. Position them in the box to ensure they do not come into direct contact with the animal containers.
4. Cold Packs
Cold packs may be necessary for some animals that could be harmed by excess heat. These packs often require several hours of preparation prior to use for shipping. Cold packs must be placed in the box to ensure they do not come into direct contact with the animal containers.
5. Secure and Label Containers
Ensure all containers are securely closed to prevent accidental escapes. Clearly label the package with “Live Animals”, “Keep Warm”, and “This Side Up” to alert handlers to its contents and special handling requirements.
6. Shipping Services
Select a shipping service that specializes in handling live animals. Overnight shipping is highly recommended to minimize the time animals spend in transit. Monitor weather conditions in advance, and avoid shipping during severe weather events. It is preferable to ship from Monday to Wednesday for delivery between Tuesday and Thursday.
7. Include Necessary Acclimation Instructions
Include instructions for the recipient on how to properly acclimate the animals upon arrival. This should explain how to gradually adjust the animals to room temperature to prevent shock.
8. Communicate
Stay in touch with the shipping service to track the shipment’s progress. Share the tracking information and estimated arrival times with the recipient to ensure someone is available to receive the package.
Conclusion
Shipping reptiles, amphibians, fish, and invertebrates requires care and attention to weather conditions throughout the year. By following these guidelines, you can help ensure that animals arrive at their destination safely and in good health. Careful preparation and consistent communication are essential!
