🐢💨 Sea Turtle Secrets: How They Breathe Underwater Although sea turtles spend most of their lives in the ocean, they are air-breathing reptiles. They must surface to inhale, yet they are capable of remarkably long and efficient dives — a fact supported by scientific research in marine physiology. 🌊✨ How do sea turtles manage it? • Highly efficient lungs: They can take a full breath in 1–2 seconds, exchanging 80–90% of the air in their lungs — far more than humans. • Oxygen conservation: Durin

#Seaturtles are air-breathing reptiles that have lungs, and will regularly come to the surface to breathe during active hours. However, they are known to stay underwater for much longer periods of time while sleeping. This one was trying so hard to stay awake, but his head kept falling forwards and backward until he finally gave in. 🐢💤 🎥 by Jacinta Shackleton Videography and Photography | Science Channel
