The most common exotic pets are also the most likely to get released into the wild

Researchers have found that some of the most common reptiles and amphibians that people own as pets are also the most likely to be released into the wild.

The exotic pet trade is the main way non-native reptiles and amphibians get moved around to new places. If people let them go in the wild, they could become new invasive species.

Oliver Stringham is the lead author of a studyin the Journal of Applied Ecology, and a PhD candidate at Rutgers University. He and his colleague Julie Lockwood looked at 1,722 species of reptiles and amphibians.

“Our study looked at the characteristics of species that were released, and we found that species that were large and were sold at cheaper prices, were more likely to be released,” Stringham says.

He says that might mean a pet that starts out little and cute gets larger than its owner expected, and he says people might place less value on animals that cost less, and be more likely to let them go.

Stringham says some solutions are for retailers to educate people on the risks of releasing pets, and to encourage people to bring unwanted pets to exotic animal shelters (he recommends looking on Petfinderfor shelters near you, and he says you can learn more about caring for reptiles and amphibians here).
