Great news for those of us that keep reptiles as companions or simply are interested in them!

Also, perhaps, somewhat worrisome.

There is substantial evidence, from two completely different and disparate parts of the globe (Louisiana, USA, and India), that some reptilians, specifically alligators and crocodiles, use tools to attract and capture prey.

As in, go hunting for dinner by utilizing implements.

Both species (American alligators and Indian mugger crocodiles) displayed the use of sticks to lure nesting birds, who go after the sticks to use for their version of Home Improvement. This behavior occurs only during nesting season, and only in proximity to the birds that do actual nesting. The thought is that useful sticks to employ for nesting material are in less supply at this time (apparently birds even get into tussles to acquire them). The birds that are hapless enough to pursue the sticks and twigs without checking what might be lurking nearby…turn into crocodilian supper!

This implies:

--These reptiles pay attention

--They use what they have handy (clawsy?) to get what they need

--They show evidence of what humans have long considered higher brain functioning. That is, they are far more intelligent than has been thought.

So, overall, we herp-intrigued people can be happy to know these creatures are much more complex than may have been previously imagined.

But please, folks. Don’t show a gator a gun!

What could be better, amongst high tech aficionados, than 3-D printing? Why, 3-D printing that makes life better for reptiles, of course!

A recent article shone a spotlight on a scuted creature in distress that was assisted in a very hard-shelled way by this new technology. It seems that Moses, a Gulf coast box turtle at the Mississippi Aquarium in Gulfport, was utterly immobile, as it was missing its two back legs. Cue a colleague of its keeper, who goes by the redditor moniker of jawscritters, as well as jawscritters’ enthusiastic reddit 3-D printer community. Their suggestions led to Moses being equipped with a 3-D printed wheelchair that allows him to scoot around with ease. The rear wheels are held in place by means of a harness strapped over the domed creature’s shell.

And it really does mean the turtle goes…zoom!

The article details other recent creative tech solutions to reptilian problems. One creation mentioned was a LEGO wheelchair designed to help heal a turtle’s cracked shell without the risk of further injury. A LEGO car kit replaced another turtle’s missing back legs with a pair of wheels that would be the envy of many a toy-car enthusiast. And a 3-D printed harness helped weigh down yet another turtle suffering from…well, bubble-butt syndrome (Yes, it afflicts turtles too, though differently than it does humans).

Even better for others who might find a terrapin in similar need: the designs used for Moses’ wheelchair have been made public online, so they are available to all.

Let’s hear it for those who put their love of tech to such a kind and worthy cause!

Researchers in China recently came upon what they initially believed to be a new species of salamander. It was…but the creature turned out to be an old, if elusive, friend.

According to an article published last year, the creature, now designated Hynobius bambusicolus (aka the Fujian bamboo salamander), was first discovered in 1978. Observers at the time only got a fleeting glimpse of the amphibian, a "dark-chocolate-colored" creature that blended in with the mud in its habitat--the blue speckles on its underside would only be discoverable if it were unhappily overturned. It then disappeared—at least to those who sought after the creature—and was supposed to have gone extinct.

Surprise! Over 40 years later, researchers exploring a bamboo forest in the area stumbled across the salamander once more, lurking in the mud and under leaf litter, logs and other typical amphibian habitat. Their surmise that this was indeed a new species was confirmed by DNA testing, which proved the Fujian bamboo salamander was genetically distinct from other species in the area. These salamanders are also unique in their ability to vocalize, emitting a short squeak or "alarm call" when probed (Can you blame them?).

Hynobius bambusicolus is a large creature (reaching up to 71/2 inches) and, with estimates of only 200 individuals extant in the wild, is considered critically endangered. This is especially true because, ahem, it has been observed cannibalizing its kin! Scientists recommend its habitat remain as undisturbed as possible, with people encouraged not to collect or otherwise engage with the population.

Welcome, new old friend! We hope you flourish in private. And find other things to eat!

Amphibians have been much on our minds recently here at RARN.

The first story, dating from a few months back, is that of the newly-designated Kermit frog. This is, alas, not a creature we 21^st-century folk will ever actually stumble across. What was discovered is actually a frog's fossilized skull, 270 million years old, with a "cartoonishly wide-eyed face" that reminded researchers of everyone's favorite Muppet, Kermit the Frog. While the fossil of the proto-amphibian was excavated in Texas quite some time ago, it was only "rediscovered" in 2021 by a scientist doing his digging in the archives of the Smithsonian! The researchers came up with the iconic name, Kermitops granus, as a way to connect the modern public with the work of paleontologists. Good job!

Our second saga concerns the annual Frog Jumping Jubilee, held with much fanfare in the charming Gold Rush town of Angels Camp, California. 2024's contest was won by The Frog Father, which was encouraged (but not browbeaten) by its sponsor Lillian Fasano to finish with a record-nearing triple jump totaling 20' 5 ½"! This contest, going back many decades, was spawned by the story "The Celebrated Jumping Frog of Calaveras County" by America's great author and satirist, Mark Twain. The success of the short story (published in 1865 during Twain's stay in the Mother Lode country) is credited with jump-starting (pardon the pun) Twain's career as writer and orator. Though the event is not without its controversies—many are skeptical of the exploitative nature of the contest—it is much less hard on the frogs than in Twain's tall tale!

And finally, on an up-close-and-personal note: just this week, a wee froggie (that's him or her in the photo) came to us at RARN. It was rescued by a kind fellow in Hollywood who happened to spot this cute-as-the-Dickens interloper near his fig tree and brought it to us. Our sharp-eyed president quickly identified the thumbnail-sized creature as an invasive species: a Cuban tree frog. After a bit of research, we found out that these guys have been spotted all over the place in Los Angeles, along with other tourist herps that are also apparently trying to make their Hollywood dreams come true. We will be on the lookout for more of these creatures! (And maybe you should too!)

In 2023, scientists and researchers recorded many fascinating creatures to add to our knowledge about life here on the planet. Among the nearly 1,000 new species discovered by the research team of the London Natural History Museum and the California Academy of Sciences were, not surprisingly, a number of reptiles and amphibians. But what a lineup!

The herpetological riches include the so-called "groins of fire" tree frog found in Peru, a nonvenomous snake also from Peru named after actor Harrison Ford (it's not his fault), a snail-eating snake from Ecuador named BY actor Leonardo di Caprio to honor his mother (aww), a croakless amphibian--the spiny throated tree frog from Tanzania--who may mate by touch (!), the lesser thorn-tailed gecko, found in western Australia, that can shoot…goo out of its tail, and a new species of legless skink found in the high mountains of Angola.

The articles reporting these revelations discuss only some of the complexities of these new discoveries from both plant and animal kingdoms. Some species were truly unknown. Others are rediscoveries of species thought extinct but which are in fact still hanging on for dear life. Other discoveries involve species which ARE extinct but because of their fossil traces, we now know about them. (Which is something, at least). Included in the discoveries are the Sierra Nevada red fox, thought extinct since 1930 (wrong!), several species of long-extinct bats, a monstrously large spider, a lightbulb anemone, a blind subterranean catfish, an oddly-snouted furry hedgehog (yes, you read that right), and a giant penguin--also sadly (but not surprisingly) extinct.

The announcement came in time to commemorate the 50^th anniversary of the Endangered Species Act in the United States. It also highlighted the importance of the act in the face of ongoing species devastation due to pollution, habitat loss, climate change, and deforestation.

Let us hope that 2024 brings other discoveries of all kinds of plant and animal life. And may it also bring humankind's renewed commitment to respect and protect the diverse living creatures that share the planet with us!
