Scuba-diving #lizards use bubble to breathe underwater, avoid predators https://phys.org/news/2024-09-scuba-lizards-underwater-predators.html
Novel rebreathing adaptation extends dive time in a semi-aquatic lizard https://royalsocietypublishing.org/doi/10.1098/rsbl.2024.0371
Lindsey Swerk: "We know that they can stay underwater for a really long time. We also know that they're pulling oxygen from this bubble... this is the first experiment that truly shows the significance of bubbles. Rebreathing bubbles allows lizards to stay underwater longer."
@animalculum do they scrub some of their exhaled CO2 into the water?
