Sea Turtles:
* Yes, they can stay underwater for a long time. Sea turtles have adaptations that allow them to hold their breath for hours. Some species can stay submerged for up to 5 hours!
* How they do it: They have a special ability to slow their heart rate and reduce their metabolism while underwater. They also have a large lung capacity.
Freshwater Turtles:
* They can stay underwater for a shorter period than sea turtles. They usually need to surface for air every 15-30 minutes.
* Exceptions: Some species, like snapping turtles, are known to stay submerged for longer periods, even up to an hour, but this is not typical for most freshwater turtles.
Other Factors to Consider:
* Temperature: Colder water allows turtles to stay submerged longer, as their metabolism slows down.
* Activity: Active turtles use more oxygen and need to surface more frequently.
* Individual Differences: There can be variation between individuals of the same species.
Important: It's crucial to remember that all turtles need to breathe air. Even though they can stay underwater for a while, it's important to provide them with access to the surface for regular breathing.
