It’s the 1980s and the Teenage Mutant Ninja Turtles franchise has burst onto the scene, scoring millions of young fans.   Half-human, half-turtle fighters Donatello, Leonardo, Raphael and Michelangelo originated as comic book characters before spawning phenomenally popular films and cartoons.   But “turtlemania” also inadvertently sparked a pet craze that ultimately led to an invasive species problem.   Red-eared terrapins were a particularly popular pet. But many people didn’t realise they would grow from a matchbox-sized hatchling to a dinner-plate sized adult that lives for more than 40 years.       As a result a significant number of freshwater turtles were illegally released in the late 80 and 90s.  Rosie joins Turtle Tally UK’s Suzie Simpson to uncover the wild origin story of how invasive freshwater turtles became a familiar sight in our waterways.   [Ad] Wild Tales is sponsored by Cotswold Outdoor, your outside retailer and epic guides to adventure.      Quick breathers, calming walks or heart-pounding hikes.
