To millions of fans around the world, Saul Hudson—universally known as Slash—is legendary as the iconic, top-hat-wearing lead guitarist of Guns N’ Roses, a band frequently dubbed the most dangerous rock group in history. Yet, music tells only one part of the storied life of this celebrated artist. For the vast majority of his life, Slash has harbored a deep, lifelong fascination with reptiles, maintaining a passionate and enduring commitment to supporting zoos, museums, and natural history institutions.
Now, that decades-long passion has unexpectedly earned him a unique and permanent scientific distinction. A team of international researchers has officially named a newly identified snake species discovered in the remote tropical forests of New Guinea Lielaphis slashi, commonly referred to in English as Slash’s groundsnake.
For the rock legend, the recognition came as an absolute surprise, bridging his lifelong love for herpetology—the scientific study of reptiles and amphibians—with his mainstream global fame.
"As a long time herpephile, I am extremely honored and humbled to have Lielaphis slashi from New Guinea named after me," Slash remarked upon learning of the scientific dedication. "It is really exciting, I never would have imagined this moment would arrive."
A Childhood Connection to Slash
For Sara Ruane, the Field Museum’s Associate Curator of Herpetology and the senior author of the research paper describing the new species in the scientific journal Zootaxa, the naming carries a profound and deeply personal significance that stretches back to her childhood.
"Guns N’ Roses has been one of my favorite bands since I was in first grade, and by fifth grade, I had already told my teacher that I wanted to be a herpetologist—a scientist who studies reptiles—when I grew up," Ruane explains. The intersection of her musical idols and her professional ambitions materialized vividly when she was just twelve years old. "So when I was twelve years old and got my copy of Reptiles Magazine in the mail and it had a picture of Slash holding his pet reticulated python on the cover, I thought, ‘This guy is so cool.’"
Years later, after Ruane had successfully earned her doctorate, established her career as a professional scientist, and attained the privilege of occasionally assigning official taxonomic names to newly recognized reptile species, she happened to look back at that formative magazine interview from her youth.
"I reread his interview, and he talked about how much he loves museums and zoos and natural history, and about how when he was a kid, he’d go outside and look for snakes—it was all stuff that I really related to, and it made me think that he’d be a great person to name a new species after," Ruane notes.
The ideal candidate for this unique scientific tribute eventually materialized from a reddish-brown snake, measuring roughly 28 inches in length, that had been collected during scientific expeditions into the lush and biodiverse forests of the island of New Guinea.
A Mysterious Snake From New Guinea
As the world’s second-largest island, trailing only Greenland in total land area, New Guinea holds immense ecological significance. Situated immediately north of Australia, the massive island is politically divided between Indonesia and Papua New Guinea. Its vast, sweeping tropical rainforests harbor an extraordinary wealth of biological diversity, a significant portion of which remains poorly documented, understudied, and entirely unknown to modern science.
The discovery of the specimen that would eventually become Lielaphis slashi took place during fieldwork conducted under the cover of darkness in 2006. Chris Austin, a professor and curator of herpetology at the Louisiana State University Museum of Natural Science, encountered a snake in the New Guinea wilderness that immediately caught his attention as something unfamiliar.
"These New Guinea groundsnakes are nocturnal, so the best way to find them is at night. They are typically found just after sunset at the base of large trees where they are looking for something to eat," explains Austin, who served as a co-author on the research paper describing the new species. "When working at night in New Guinea you need to be very careful as there are several highly venomous species that look very similar to the non-venomous groundsnakes."
The path to formally describing the species took years of collaborative scientific effort. After completing her doctorate, Ruane worked alongside Austin at Louisiana State University in 2016. The two researchers began collaborating closely to better understand the notoriously poorly studied snakes native to New Guinea, forging a professional partnership that has continued to yield significant scientific insights into the region’s unique herpetofauna.
Genetics Reveal a New Species
When the reddish-brown snake specimen was first recovered and examined, it did not immediately present obvious physical characteristics that clearly set it apart as a brand-new species to science. It was only through rigorous, detailed laboratory analysis that the crucial genetic and morphological differences came to light.
"Using multiple cutting-edge genetic analyses, we found that L. slashi is genetically distinct from other similar snakes in the same genus," says Tianqi Huang, the study’s first author and a post-doctoral researcher at the Field Museum working alongside Ruane. "The combination of physical characteristics, like differences in numbers of scales when compared with other species, and the genetic evidence is what led us to realize that it is an entirely new species. We also used ecological modeling to show that L. slashi’s preferred habitat is different from similar snakes."
The research team successfully integrated robust genetic evidence with careful examinations of physical traits—including distinct variations in scale counts—to definitively distinguish L. slashi from closely related snakes within the region. Furthermore, advanced ecological modeling confirmed that the newly identified species occupies a distinct ecological niche, favoring a different type of habitat compared to similar members of its broader taxonomic genus.
What Slash’s Groundsnake Eats
Despite the breakthrough in identifying and classifying the animal, scientists acknowledge that they still know relatively little about the comprehensive behavior, daily habits, and broader ecology of Slash’s groundsnake in its natural environment.
"It’s incredibly hard to observe snakes in the wild before they slither away, so our knowledge about L. slashi is limited," Ruane admits.
Nevertheless, a careful examination of the snake’s internal and external anatomy provides valuable clues regarding its lifestyle, foraging habits, and predatory mechanisms.
"Snakes in this genus often have large teeth in the back of their mouths, which New Guinea groundsnakes may use to grab on to and eat small, slippery-scaled lizards and the eggs of other reptiles; this snake isn’t grasping and squeezing its prey like a boa constrictor," Ruane explains.
While Guns N’ Roses may have earned international notoriety as the "most dangerous band in the world" during the height of their rock-and-roll stardom, their quiet, scaly namesake poses no real danger to humans. L. slashi does not produce venom capable of causing serious harm or posing a lethal threat to a human being.
Threats to New Guinea’s Forests
While Slash’s groundsnake may be entirely harmless to people, human activity and industrial expansion pose a significant, growing threat to the survival of the species and countless other unique organisms inhabiting the fragile forests of New Guinea.
"The habitats that Slash’s groundsnake is from are under threat from industries like coffee farming and mining," warns Ruane. "That’s part of why describing the species that live there is important. Every species should be recognized in order for us to better understand how ecosystems work, how everything fits into the environment. We can’t conserve animals or other living things that we don’t know about."
By formally identifying, naming, and documenting species such as L. slashi, researchers and conservationists are able to construct a much clearer, more comprehensive picture of New Guinea’s extraordinary biodiversity. This foundational scientific work is essential for determining which vulnerable organisms may be at the highest risk as their native forest habitats continue to face environmental pressures and human-driven changes.
The formal scientific description and study of the species was made possible through the collaborative contributions of a diverse team of researchers, including Tianqi Huang of the Field Museum and Rutgers University; Chris Austin of the Louisiana State University Museum of Natural Science; Justin Bernstein of Slippery Rock University and the American Museum of Natural History; Bulisa Iova of the Papua New Guinea National Museum and Art Gallery; Jackson Roberts of the Virginia Museum of Natural History; Jeffrey Frederick of the University of Kentucky; and Sara Ruane of the Field Museum.
