Deep seas, high Andes, and ancient fossils: New species scients found in 2025 | Technology News
From the coasts of the Middle East to the crushing depths of the Pacific Ocean, researchers in 2025 have unveiled a few species that redefine our understanding of biodiversity.
Salwasiren Qatarensis
In the fossil-rich grounds of Al Maszhabiya, Qatar, scients unearthed the remains of a prehoric sea cow that roamed the Persian Gulf 21 million years ago. Unlike modern cattle, which are often cited as methane contributors, this “ecosystem engineer” was a carbon-sequestering powerhouse.
grazing on seafloor vegetation, these mammals cycled nutrients and prevented seafloor stagnation, much like modern dugongs.
Marmosa Chachapoya
During a trek through the rugged Río Abiseo National Park in the Andes, Silvia Pavan of Cal Poly Humboldt stumbled upon a tiny mouse opossum previously unknown to science.
Named to honour the indigenous Chachapoya people, this mini marsupial thrives at elevations where few other mammals survive. Its dinctively elongated snout and specific cranial structure were confirmed as unique through DNA sequencing, and Pavan warns that these mountains are under immediate threat from climate shifts, making the documentation of such species a race against time.
Siskiyu Armilla
In a surprising turn of events, biology professor Marshal Hedin discovered a new genus of spider right near his childhood home in Northern California.
Identifying this spider, Siskiyu Armilla, was no small feat; many brown spiders look virtually identical to the naked eye. It was only through the genetic analysis led Rodrigo Monjaraz Ruedas that the team realised they had found a dinct lineage. This discovery suggests that California, already home to nearly 40 per cent of the United States’ known spider species, still hides dozens of “cryptic” species beneath its rocks and leaf litter.Story continues below this ad
Bumpy Snailfish
Found drifting 11,000 feet below the surface of the Pacific near the Central California coast, the bumpy snailfish has quickly become an internet sensation. With its oversized eyes and a mouth curved into a permanent grin, it challenges the stereotype of deep-sea creatures as “monsters”.
Mackenzie Gerringer, a researcher at SUNY Geneseo, argues that “charismatic” deep-sea life helps the public connect with an environment that feels alien. Beyond its looks, the snailfish plays a role in a habitat that acts as a massive global carbon sink, making its survival a matter of planetary health.
Live-Birthing Toads of Tanzania
In the Eastern Arc Mountains, a century-old mystery was finally solved. Most amphibians lay eggs, but three newly identified species in the Nectophrynoides genus give birth to fully formed young.
This discovery was made possible a multinational team using “next-generation sequencing” on over 200 preserved specimens, some of which had been sitting in museums for decades. However, the victory is bittersweet; researcher John Lyakurwa notes that these toads are in a state of drastic decline. For instance, one of the newly named species may already be extinct.
