Escaped Pets are Ecosystems in Waiting

A few years ago, we learned that the original Teenage Mutant Ninja Turtles craze—or, rather, its rapid fizzling-out—led to a spike in illicit turtle releases in England’s Lake District. As a result, the District today is suffering through a minor invasion of orphaned turtles, unwanted pets struggling to return to a state of nature.

Zoom-in on an historic landscape in Britain, in other words, and you will find the living remnants of a 1980s pop cultural fad splashing around somewhat pathetically—somewhat sadly—in the brisk water.

Now, in thematically related news, discarded goldfish have been taking over entire river landscapes in Australia: “Two decades ago, someone dropped a handful of unwanted pet goldfish into a creek in southwestern Australia. Those goldfish grew, swam downstream, mucked up waters wherever they went and spawned like mad. Before long, they took over the whole river.”

Liberated from endless circling inside glass bowls in children’s bedrooms, the fish are able to reach their expected size, “with some fish growing as long as 16 inches and weighing up to four pounds—the size of a two-liter soda bottle.”

Indeed, the New York Times explains, “Freed from the constraints of a tank, goldfish balloon to the size of footballs. Within a few generations, they revert to natural yellow and brown colors, in place of the bright orange that breeders try to achieve.” Their success in the wild should not come as a surprise.

While there’s much more about the invasive ecology of this species over in the original article, it’s hard not to be struck by the anthropocenic absurdity of an ecosystem constituted entirely by escaped pets.

Hypertrophied beyond recognition, re-wilded by their unexpected freedom, feral pets remake the world in the distorted image of what their human owners thought nature should look like. Toy poodles will stalk our future woods.

Teenage Mutant Ninja District

Abandoned terrapin turtles purchased 25 years ago at the height of popularity for Teenage Mutant Ninja Turtles have been harming wildlife and changing the ecological character of England’s famed Lake District. Once an orbital center for the lives of poets William Wordsworth and Samuel Taylor Coleridge, the landscape is now infested with discarded pets purchased for their imaginative resemblance to kids’ toys and comic book characters.

Terry Bowes, a regional zoo director interviewed by the Guardian, has become “exasperated at the routine abandonment of creatures,” he explained, “that suffered the misfortune of becoming fashionable at the time of the Teenage Mutant Ninja Turtle craze.”

“I was thinking what we could do about them all,” Bowes told the paper, “and then I heard about another Teenage Mutant Ninja Turtle film coming out soon and steam came out of my ears. I was thinking, ‘Oh no, this is only going to get worse.'”

Human ownership of changing animal species responds to the quirks of popular appeal, we read, including hit films and toy lines: “Pets are just as vulnerable to fashion as anything else, said Bowes, as we passed three enormous European eagle owls he said were abandoned by their owners after they outgrew Harry Potter, and a trio of perky meerkats he said were probably originally bought after seeing the star of the Compare the Market insurance ads.” The region is an open-air zoo of animals that have escaped from popular media.

Surely, though, in a sense, this is just the latest, albeit inadvertent iteration of the infamous American Acclimatization Society, a group of literary-minded naturalists in 19th-century New York City who made it their bizarre goal to “introduce to the U.S. every bird mentioned in Shakespeare’s scripts.” As Scientific American writes, “The Acclimatization Society released some hundred starlings in New York City’s Central Park in 1890 and 1891. By 1950 starlings could be found coast to coast, north past Hudson Bay and south into Mexico. Their North American numbers today top 200 million.” Shakespeare, the Bible, Teenage Mutant Ninja Turtles—all cultural artifacts and unintended animal blueprints for infested landscapes yet to come.
