No this is an old joke
no they breath through their noses
All turtles breath air
No, they can not!
Turtles live in the water. How can they not breath in what they live in?!
Turtles come to the surface and breath air, before swimming below the surface until it is time to breath air again.
Turtles don't breathe under water. They've got lungs - not gills. They hold their breath when they dive.
yes
Sea turtles are amphibians, which means they breathe out of their lungs.
Most turtles slow down their breathing and hold their breath and they can hold their breath for longs periods of time.
If it is an aquatic turtle it is very difficult to tell without a side by side comparison. Aquatic female turtles have shorter claws and tails. Female land turtles have flat shell bottoms. Male box turtles have bright red eyes, curved bottoms to their shells and thin tails.
Turtles do indeed breath oxygen. They are able to hold their breath for extended periods while either hiding or search for food under water.
It depends on the turtle species. A "pond turtle" is generally just a large turtle. Most turtles can hold their breath for at least 10-20 minutes but other turtles can hold their breath for 40-50 minutes. Although they can hold their breath for a long time a lot of turtles will just come up every couple of minutes.
