Introduction
As many have noticed, axolotls are illegal to own as pets in some US states and Canadian provinces, as well as other parts of the world. In the United States, axolotls are illegal to own in California, Maine, New Jersey, and D.C., while a permit is required in New Mexico and Hawaii.
In Canada, it is illegal to own axolotls in New Brunswick, British Columbia, Prince Edward Island, while a permit is required in Nova Scotia. While this can be frustrating to those who live in locations where these bans are implemented, it is important to remember that these rules are in place for valid reasons.
The Reason Behind the Ban
Some may assume that these bans are a result of the wild axolotls being critically endangered, however this is not the case. While wild axolotl populations are in steep decline and will likely face extinction soon, the axolotls kept as pets have been fully bred for generations in captivity and are descendants of a number of small colonies spanning a few different countries.
Pet axolotls have been bred in captivity for decades, to the point where they are no longer the same as axolotls found in the wild, both genetically and behaviorally. Captive axolotls have been crossbred with tiger salamanders, have had their DNA tweaked (the GFP gene is one example), and have been bred for many generations in the absence of natural selective forces, thus making them almost like an entirely different species. This is one important reason why releasing pet axolotls into Lake Xochimilco (their native habitat) would not help prevent wild axolotls from going extinct.
The reason that many governments outlaw the ownership of axolotls comes down to the large environmental threat they pose if they ever were to be released into the wild. For example, this is the case in California where the potential release of axolotls could cause severe environmental damage.
If released into the wild, axolotls have the potential to easily outcompete already struggling native salamander species, such as the California tiger salamander (Ambystoma californiense) and the Eastern tiger salamander (Ambystoma tigrinum).
Invasive Pets
In addition to axolotls, there have already been countless instances of former pets being released and becoming established in local ecosystems, causing unforeseen harm. Look no further than the state of Florida, where a new law was passed earlier this year to ban the ownership of several reptile species that were deemed to be of high risk to the local ecosystems.
This ban did not target obscure animals, but was instead aimed at reptiles commonly kept as pets, such as tegus, green iguanas, and various species of pythons. For several years, the ecosystems of Florida have been invaded by many released pets that have outcompeted local animals to the point that some species face extinction.
Another example of escaped pets destroying the environment can be seen all across the United States. Common goldfish are one of the most commonly sold fish in the aquatic hobby. Whether they are sold as pets or feeders, these fish have devastating effects on ecosystems when released into lakes or ponds. While most people are under the impression that these are small, low maintenance fish, this is not the case.
Fully grown goldfish will reach a length of 10-12 inches (25-30 centimeters) and live to be 15-20 years old. These large carp are hardy generalists that can survive in a variety of different environments across the globe, which allows them to easily outcompete native fish. When released by pet owners, goldfish in wild waterways often outcompete local fish species driving them to extinction.
Invasive Plants and Hitchhikers
Releasing animals is not the only way that pet owners may introduce invasive species into the environment. Discarded aquatic plants can also have huge impacts on local ecosystems. Earlier this year, headlines were full of reasons to properly dispose of aquatic plants.
Across the United States and Canada, there were reports of zebra mussels, an invasive species that has already invaded several waterways across the globe, hitching a ride on marimo balls. While these hitchhikers were easy to spot, aquatic plants can also harbor less noticeable hitchhikers, such as diseases and parasites. In some cases, the discarded plants themselves may even pose a threat as invasive species.
If you have ever purchased aquatic plants, then there is a chance that you may have had a run in with duckweed. This small floating plant quickly propagates itself and can cover the surface of your tank quickly. Duckweed, along with several other plants kept in the aquatic hobby, have the potential to destroy ecosystems if not disposed of properly.
Whenever you are disposing of aquatic plants, be sure to avoid flushing them down the toilet or disposing of them in or around waterways. Instead, simply throw them in the garbage, or better yet find another hobbyist who may want your trimmings (r/aquaswap on Reddit is a great way to do this).
Conclusion
It is unfortunate that not everyone is able to own axolotls. However, the reason why most governments ban the ownership of axolotls is in the best interest of local ecosystems. For centuries, humans have been devastating ecosystems and driving animals to extinction.
Taking cautionary steps, like limiting where axolotls can be kept, helps to slow down and prevent our collective damage to the world around us. After centuries of destruction of natural habitats, the least we can do is obey these laws and do what we can to ensure captive animals and plants are not released into the wild.
I think we R saving Axolotls because they need a home. And I personally hate the vids on YouTube that people cut off their arms and eat them!👹😡😡😡😡😡😡🤬🤬🤬 it makes me feel like throwing the keyboard at the I-pad.
If yall REALLY love axolotls, then you would want them to be thriving in their natural habitat in the wild. You would care about environmental conservation & helping to prevent ecosystem/environmental destruction. I think its selfish for all these humans to want an axolotl or any other exotic or rare creature as a pet just because they're "so so so cute". The most selfless thing we can do as the human species is to protect our environment & all the creatures in it. Join causes that actually help clean up our earth, oceans, rivers, lakes, forests, etc. Make choices in your everyday life to reduce your plastic waste, reduce or nullify your carbon emissions, etc. The wild, natural Axolotl yall…
