Scuba Gear Lizard Can Breathe Underwater
Lizards residing in the Costa Rican Rainforest, known as diving anoles, can store oxygen as they dive and breathe underwater, just like scuba divers. These scuba lizards trap a little air bubble on their heads that covers their nostrils, allowing them to breathe while hiding from predators underwater. The lizards can stay submerged for several minutes, giving them a survival edge and making them unique in the world of biology.
What’s really fascinating about these scuba diving lizards is that multiple species in the Anolius genus exhibit the behavior. All of the lizards that exhibit the diving behavior are from the same area, and they’re all aquatic, living their lives on land as well as water.
The only other animals that exhibit underwater breathing behavior like this are arachnids and insects, but scuba lizards are the only vertebrates to exhibit this ability.
Since anole lizards aren’t very fast, their main defense against predators is their camouflaging ability. When that fails them, hiding underwater is the scuba lizard’s best defense. This strategy of waiting out their would-be predators is a mysterious behavior that researchers are endeavoring to find the origins of.
Hiding underwater is the scuba lizard’s best defense.
To get a better look at the scuba lizards’ bubble-breathing, Dr. Lindsey Swierk, a researcher from Binghamton University in New York, captured several A aquaticus anoles. Working at the Costa Rica Las Cruces Biological Station, she placed the scuba lizards in a clear tank to observe their bubble breathing. One group of lizards was dabbed with an emollient to prevent them from keeping air bubbles on their snouts, and the other was left as they arrived.
The lizards in the control group, who weren’t treated with emollient, all had large air bubbles they used to breathe underwater while the ones who were dabbed produced smaller air bubbles or none at all.
The scuba lizards who had emollient on their snouts couldn’t get their bubbles to stick, so they couldn’t perform their regular scuba behavior. All of the lizards used their throat muscles to pump oxygen into their lungs.
On average, the scuba lizards could stay submerged for three and a half minutes
The bubbleless lizards had to resurface a little more than a minute sooner than the scuba lizards did. On average, the scuba lizards could stay submerged for three and a half minutes, and the non-bubble lizards could stay under for just short of two and a half minutes.
This bubble breathing technique is an advantage as the diving anoles can evade predators for a longer period of time.
The downside of diving for lizards is that it can cause their body temperature to drop. The chilly water the scuba lizards are hiding in can cool the animals down faster than if they were on the surface. This chilling effect can make lizards slower when they emerge from the water and less able to run from predators.
Exactly how the lizards are able to hold onto their air bubbles and how this ability developed across multiple species is still not clear. Researchers are hoping to put together a better explanation for the unique behavior of the scuba lizards by studying video and statistics from their recent experiments.
They have posited that oxygen could potentially diffuse through the bubble, allowing the lizards to breathe for longer through the bubble than was previously assumed.

Star Trek’s Most Ambitious Villain Helped Create The Franchise’s Most Complex Hero
By Chris Snellgrove
| Published
When Star Trek: Voyager first came out, the most fascinating character was the Doctor. While Robert Picardo’s performance was superb, it’s fair to say this character was mostly fascinating on a conceptual level. We had seen things like hypercompetent Starfleet captains and exotic aliens before, but what we hadn’t seen was a fully holographic chief medical officer. Voyager’s Emergency Medical Hologram seemed like the perfect embodiment of the Star Trek ethos. He’s a technological strange new world and new life, all rolled into one.
However, what casual audiences didn’t realize is that the Doctor wasn’t completely unique. Long before Picardo’s character ever sawed bones in the Delta Quadrant, Captain Picard dealt with another extraordinary hologram: Moriarty, the brilliant foe of the famous investigator Sherlock Holmes. Over on The Next Generation, Geordi LaForge accidentally created this villain as a sentient hologram when he asked the holodeck to create a challenge worthy of the android Data. Later, Star Trek: Voyager executive producer Jeri Taylor revealed that, in-universe, the holographic Doctor was created because Starfleet took advantage of the same accidental breakthrough that created Moriarty!
It all started in “Elementary, My Dear Data,” the Next Generation episode in which the titular android and Geordi LaForge recreated Sherlock Holmes’ adventures on the holodeck. Thanks to his positronic brain and his encyclopedic knowledge of Sir Arthur Conan Doyle’s Holmes novels, Data is able to easily solve every mystery that is thrown at him. That’s when Geordi makes a seemingly simple request. He asks the Enterprise computer to develop a holodeck foe that could actually defeat Data, one of the smartest beings in the entire galaxy.
The computer obliges and creates a sentient version of Moriarty, Sherlock Holmes’ greatest foe. Following Geordi’s instructions, the Enterprise computer included much of Data’s vast programming, which resulted in the holographic character becoming self-aware. Moriarty ended up threatening the Enterprise on two different occasions, and Picard eventually got rid of him by trapping the unknowing villain in a simulation where he thought he had left the holodeck and could explore the stars. This was meant to be a happy ending for Moriarty, but in the show’s typically bleak fashion, Star Trek: Picard later showed us a different, more hostile version of this character created by a malevolent Section 31 AI.
How A Villain Created A Hero
What does all of this have to do with Robert Picardo’s holographic Doctor on Star Trek: Voyager? Elementary, my dear reader! Very early in Voyager’s development (the show didn’t even have a name yet), executive producer Jeri Taylor was inspired by Moriarty to create a new character. As reported in A Vision of the Future-Star Trek: Voyager, Taylor wrote down notes for a holographic doctor “who, like Moriarty, has ‘awareness’ of himself as a holodeck fiction. He longs for the time when he can walk free of the Holodeck.”
A few days later, she wrote down additional notes that contain a startling bit of Star Trek lore. “The Holo-Doctor represents a new, state-of-the-art technology which has capitalized on the serendipitous incident which created Moriarty, and has programmed a holographic character which has self-awareness of his situation and limitations.” While Moriarty is name-dropped on Voyager a couple of times, the show never mentioned what Taylor’s notes seem to confirm: that Lewis Zimmerman could never have created the Emergency Medical Hologram program if not for Geordi LaForge accidentally creating Moriarty on the holodeck.
From Villain To Leading Man?
If that’s not strange enough, there was a period of time when Voyager’s producers were considering making Moriarty a mainstay character on the show. As reported in Star Trek–Where No One Has Gone Before, Taylor’s notes mentioned that “everyone agreed that was a little too broad, and we couldn’t figure out why anyone would take him along.” After dismissing the idea, they decided “that having a holographic doctor with the full consciousness of being a hologram might be fun, and we’d never done anything like that before, except for Moriarty.”
There you have it, gentle reader. Without the character of Moriarty on Star Trek: The Next Generation, we’d never have the Doctor on Voyager. In this way, Trek’s most ambitious villain helped create the franchise’s most complex hero. Thanks to Jeri Taylor’s notes, we also know that, in-universe, Lewis Zimmerman would never have been able to create the Doctor if not for Geordi accidentally creating a sentient Moriarty so Data could have fun. In retrospect, this does make Zimmerman’s arrogance that much weirder. After all, he has a lot of attitude for someone who owes his entire career to the two biggest book nerds in the galaxy!
