And because anoles are so well-researched, they present scientists with the chance to ask highly nuanced questions about anoles' evolution , biology and behavior, Dappen explained.
One of those deep-diving questions was about the diving Costa Rican river anole and what exactly was happening after they jumped into the water, remaining there for as long as 15 minutes. Herpetologist Luke Mahler, an assistant professor of ecology and evolutionary biology at the University of Toronto, urged the filmmakers to look closely at their underwater footage when they filmed the anoles, to see if they could identify any clues that would explain what the river anoles were doing.theranchhands.com/images/little/geotechnical-and-geophysical-site-characterization-4.php

While Dappen and Losin didn't see anything out of the ordinary when they first reviewed the video, they watched it more closely after they returned to the United States. That was when they noticed something remarkable. What they observed was astounding.
As a submerged female anole crouched on the river bottom for nearly 10 minutes, a tiny bubble repeatedly expanded and contracted at the top of her head. The lizard appeared to be recycling her air, much as a human diver would draw on oxygen from a tank. Presumably, re-breathing stored air would enable river anoles to remain underwater long enough for them to outwait threats on land, Dappen explained.
Drawing on air caches is known to occur in some invertebrates , such as diving bell spiders and diving beetles, but this may be the only example of re-breathing in land animals that have backbones, Losin said.
If water is made up of hydrogen and oxygen, why can't we breathe underwater?
How the river anoles accomplish this feat is still uncertain, but Mahler and his colleagues are currently investigating the mechanics of the behavior, Losin told Live Science. The device uses "artificial gills", a filter with holes smaller than water molecules but large enough for oxygen to pass through. However, several articles have been published which are skeptical about whether the device would actually work. Writing for Deep Sea News in , Dr. Alistair Dove, director of research and conservation at Georgia Aquarium, estimated that the device would need to filter 90 litres of water a minute to provide enough oxygen for the user.
Following several inquiries about the device and articles questioning whether the device worked as claimed, the company relaunched the campaign at the end of last week and refunded all their supporters. In an effort to increase transparency and clarify how the device worked, Triton's developers revealed the device requires a cylinder of 'liquid oxygen' to provide enough breathable oxygen for the user. The cylinder will need to regularly replaced. This is the way Triton can produce enough oxygen for a human to breathe from.
Triton also posted a minute video to Youtube showing a man sitting underwater using the device to further support their claims. Despite this, many remain skeptical.
Stephan Whelan, founder of online diving community DeeperBlue, has warned people against supporting the campaign.
