Aquatic turtles — including red-eared sliders, painted turtles, and map turtles — are among the most widely kept reptiles worldwide, yet welfare standards are often poor and wild population impacts from the pet trade are significant.
Aquatic turtle welfare in captivity fails most commonly due to inadequate space, missing UV lighting, poor water quality, and incorrect temperature ranges. The long lifespan of turtles means welfare neglect compounds over decades. The release of unwanted pet turtles into wild waterways has created invasive populations across Europe, Asia, and Australia, harming native aquatic ecosystems. Responsible ownership and adoption rather than purchase are key welfare interventions.
