Scientists discover first new penguin species in more than 100 years
Genome sequencing and behavior comparisons show the birds are one of four gentoo species, ending a century of debate over their classification.
- An international team led by researchers in Chile and at the University of California, Berkeley identified four distinct Gentoo species, marking the first new penguin species named in more than 100 years.
- Genetic evidence reveals these populations diverged between 300,000 and 500,000 years ago, driven by geographic isolation and the Antarctic Polar Front, a major boundary in the Southern Ocean that restricts marine animal movement.
- The consensus, published in Communications Biology, utilized whole-genome sequences from 64 penguins across 10 breeding colonies; their flexible diet encouraged populations to remain near nesting sites, promoting speciation.
- While the Antarctic southern Gentoo may expand its range, the newly recognized southeastern Gentoo faces an uncertain future, prompting Juliana Vianna of Bello National University to emphasize conservation action across multiple nations.
- Climate models suggest sub-Antarctic Gentoo species could lose suitable habitat by 2050; Bowie noted that whole-genome sequencing has "really important conservation value," helping scientists identify genetic traits linked to avian influenza resistance.

First New Penguin Species in a Century Found on Kerguelen
For most of the last hundred years, biologists have argued about how many kinds of gentoo penguin exist. Some argued for one species with a scatter of subspecies. Others insisted there were four, or five, or six separate lineages. The argument never ended, because the birds themselves would not settle it. They look almost identical, […]
Pygoscelis papua (Pygoscelis papua), which looks very close to the new species gabriel_delasala / iNaturalist For more than a century, specimens of a penguin living in the remote Kerguelen Islands, in the south of the Indian Ocean, were before the eyes of science without being formally recognized as a species of its own. Treated within the complex of the gentoo penguins, these animals hid evolutionary differences that now led researchers to desc…
Researchers identified the new penguin species through DNA testing, while the Kerguelen Islands, climate change and the future of the species also came into focus.
A population of penguins from the remote Kerguelen Islands, in the southern Indian Ocean, was formally described as a new species. Baptized from Pygoscelis kerguelensis, it would be the first species of new penguin for science recognized in more than one s
Scientists discover first new penguin species in more than 100 years
Genetic evidence has revealed a previously unknown gentoo penguin species on the remote Kerguelen Islands and shown that gentoos actually consist of four distinct species. The discovery also highlights a growing threat, as warming oceans could leave several island populations with little suitable habitat by 2050.
Scientists from Chile, the United States, and other countries have identified a new species of gentoo penguin, living on the remote Kerguelen Islands in the southern Indian Ocean. This is the first newly named penguin species in over a century. The findings were published in the journal Communications Biology and were shared publicly by Science Daily.
