We’ll continue updating this running list of some of the new and rare species discovered — or rediscovered — throughout 2024.

But with over 157,000 species on the IUCN Red List of Threatened Species, 44,000 of which are at risk of extinction, news of new animal and plant species being discovered can feel few and far between.
Thankfully, conservation efforts can help with that. Not to mention, every year, scientists reportedly discover 18,000 new species — so throughout 2024, we’ll be updating this list with some of the most exciting new species that are unearthed. Stay tuned!
The Coapilla arboreal alligator lizard, aka Abronia cunemica
In early January, researchers published a study in the journal PLOS One detailing their discovery of a new lizard species. The species was first observed in photos in Chiapas, Mexico’s Northern Highlands in 2014; and then between 2015 and 2022, the researchers took five trips to the site to collect evidence.

Their expeditions were worth it, as they can now officially call Abronia cunemica, aka the Coapilla arboreal alligator lizard, a species. As noted by The Miami Herald, the species lives up high in trees, has brown-and-yellow scales, and can grow up to more than 9 inches in length.
A new jaguar in the U.S.
In early January, it was announced that a new jaguar was spotted in Arizona in December 2023. In the last 30 years, this marks only the eighth jaguar recorded in the Southwestern U.S.
“I’m certain this is a new jaguar, previously unknown to the United States,” Russ McSpadden of the Center for Biological Diversity said, as per AP News. Experts were able to determine this by the jaguar’s unique rosette pattern.
“After being nearly wiped out, these majestic felines continue to reestablish previously occupied territory despite border wall construction, new mines, and other threats to their habitat,” McSpadden added.
According to the the Center for Biological Diversity, the U.S. Fish and Wildlife Service classified jaguars as endangered in 1972; then, in 1980, they were removed from the list. As populations waned, come 1997, jaguars were added back to the endangered list. So while this sighting does not mark a new species, it’s just as remarkable, as it’s a sign of the jaguar population rebounding.
