The eastern painted turtle's diet is the least studied. It prefers to eat in the water, but has been observed eating on land. The fish it consumes are typically dead or injured. [120] The midland painted turtle eats mostly aquatic insects and both vascular and non-vascular plants. [123]
Turtles can rest or sleep underwater for several hours at a time, but submergence time is much shorter while diving for food or to escape predators. Breath-holding ability is affected by activity and stress, which is why turtles quickly drown in shrimp trawlers and other fishing gear. [112]
Older turtles may occasionally seek prey as well, but mostly partake of a herbivorous diet. [6] These turtles can sometimes be found basking in the sun, but are very wary and will quickly retreat into the water if approached. Otherwise, they are difficult to find in the water, which may be due to their ability to breathe while fully submerged.

Painted turtles hibernate buried in mud or underwater and do not resurface for the entire winter. As a result, they rely on lactic acid fermentation to provide the majority of their energy needs. [23] Adaptations in particular in the turtle's blood composition and shell allow it to tolerate high levels of lactic acid accumulation.
Some turtles, especially those specialized in diving, are highly reliant on cloacal respiration during dives. [2] They accomplish this by having a pair of accessory air bladders connected to the cloaca which can absorb oxygen from the water.
