Please don’t “rescue” baby turtles of any kind unless they’re noticeably injured!
There is no such thing as an orphan turtle. Unlike mammals, birds, and a couple of reptiles, turtles do not care for their young at all. A mother turtle lays her eggs and never sees them again.
Well-meaning people who “rescue” turtles from the wild aren’t doing them any favors: without UV lighting, spacious habitats, and an extremely carefully balanced diet, turtles brought into captivity don’t survive. A young turtle is more likely to die in captivity than in the natural world where it belongs.
However, if you spot a baby turtle trying to cross a road, please help it cross in the direction it’s going! You can also give wild turtles a hand by keeping your pets indoors or leashed when you know there are young turtles around.
