A creature built for a world of stone and soil
A sessenta metros abaixo da superfície australiana, a ciência encontrou aquilo que o próprio nome sempre prometeu mas nunca havia cumprido: um milípede com mais de mil patas. A espécie Eumillipes persephone, descoberta numa região mineira da Austrália Ocidental, reescreve um registo que resistia há décadas e lembra-nos que a Terra guarda ainda criaturas moldadas por pressões evolutivas que mal conseguimos imaginar. A sua existência, porém, é tão frágil quanto extraordinária — ameaçada pela mesma atividade humana que a trouxe à luz.
- Pela primeira vez na história da ciência, um milípede cumpre literalmente o seu nome: 1.306 patas em apenas 95,7 milímetros de corpo.
- A criatura vive sem olhos a sessenta metros de profundidade, num mundo de pedra e escuridão onde a maioria dos animais não sobreviveria.
- A descoberta expõe uma ironia perturbadora: foi a mineração que revelou a espécie, mas é também a mineração que pode extingui-la.
- Os investigadores publicaram os resultados em Scientific Reports e já apelam a medidas urgentes de proteção do habitat subterrâneo onde o animal existe.
No fundo de um furo de sondagem numa mina da Austrália Ocidental, a sessenta metros de profundidade, cientistas encontraram uma criatura que parecia pertencer mais ao mito do que à biologia: o primeiro milípede verdadeiramente merecedor do nome. Batizada de Eumillipes persephone, a espécie possui 1.306 patas distribuídas por 330 segmentos corporais, superando em mais de metade o recorde anterior, detido por uma espécie californiana com 750 patas.
O animal é de uma delicadeza quase impossível. Com menos de 96 milímetros de comprimento e menos de um milímetro de largura, assemelha-se a um fio segmentado. Não tem olhos — não precisaria deles —, mas compensa com antenas desenvolvidas e uma pequena estrutura bucal em forma de bico. A sua anatomia é uma resposta precisa ao ambiente: os inúmeros segmentos e patas geram a força propulsora necessária para atravessar fendas subterrâneas onde nenhum outro animal conseguiria passar.
A descoberta, publicada na revista Scientific Reports, revela também que esta acumulação extrema de segmentos evoluiu de forma independente em ecossistemas isolados, já que Eumillipes persephone e o seu congénere californiano pertencem a ordens distintas. A evolução chegou à mesma solução por caminhos separados.
Mas a história não termina em celebração. A operação mineira que expôs esta espécie ao mundo é a mesma que ameaça o seu futuro. Os investigadores alertam agora para a necessidade de proteger o habitat subterrâneo da Eastern Goldfields, antes que uma criatura que demorou milhões de anos a surgir desapareça em poucas décadas.
Deep in an Australian mine shaft, sixty meters below the surface, scientists found something that had eluded researchers for centuries: a creature with more than a thousand legs. The newly identified species, named Eumillipes persephone, holds a distinction that sounds almost mythical in its specificity—it is the first millipede ever documented that actually deserves the name. With 1,306 legs distributed across 330 body segments, it shatters the previous record by more than half.
The animal itself is almost impossibly small. At just under 96 millimeters long and less than a millimeter wide, it resembles a thread more than a creature. Its body is a thin, segmented line. The head tapers to a cone shape and bears no eyes, but compensates with enormous antennae and a small beak. Everything about its anatomy speaks to a life lived in absolute darkness, in spaces so tight that most animals could never navigate them.
The discovery came from Eastern Goldfields, a region in Western Australia where mining operations had created the borehole that exposed this hidden world. Before Eumillipes persephone, the record holder was Illacme plenipes, a Californian arthropod with 750 legs—still remarkable, but not quite the threshold that the word millipede literally promises. Both creatures belong to the same broader arthropod family, but to different orders, suggesting that the evolutionary pressure to accumulate legs and segments has emerged independently in isolated underground ecosystems.
The researchers who documented this find, publishing their work in the journal Scientific Reports, offer a compelling explanation for why such extreme segmentation evolved. The sheer number of legs and body segments generates propulsive forces that allow these animals to squeeze through impossibly narrow passages in their subterranean homes. In the tight, labyrinthine spaces where they live, this ability to compress and push through crevices becomes a survival advantage. The creature is built for a world of stone and soil, where conventional locomotion would fail.
But the discovery carries an uncomfortable irony. The very mining operation that exposed Eumillipes persephone also threatens it. The researchers who identified the species are now advocating for habitat protection, urging that conservation efforts be made to preserve the underground environment where this animal lives. A creature that took millions of years to evolve, that exists nowhere else on Earth, could vanish within decades if the landscape that sustains it continues to be excavated. The millipede with over a thousand legs may have finally been found, but its future remains precarious.

The Hearth Conversation Another angle on the story
Why does it matter that we found this particular millipede? There are thousands of arthropod species.
Because it's the first one that actually earns the name. For centuries, "millipede" meant something that wasn't quite true. Now we have proof that the form can exist.
But it's so small—less than a centimeter long. How does something that tiny even survive?
Size is irrelevant in the spaces it inhabits. In a narrow crack in stone, being thread-thin is an advantage. It moves through gaps nothing else can reach.
The researchers mentioned that mining exposed it. Does that mean mining destroyed its habitat?
Not yet, but the threat is real. The borehole that revealed the creature also opened its world to disturbance. The scientists are essentially saying: we found this, now we need to protect it before we lose it.
Why did evolution give it so many legs when it's so small?
Each leg is attached to a segment. More segments mean more flexibility, more ability to undulate through tight spaces. It's a trade-off—you gain maneuverability in confined spaces, but you're locked into that niche forever.
Is there anything else like it?
One other species comes close—the Californian millipede with 750 legs. But this one is different, from a different order. It suggests that wherever you have deep, isolated underground ecosystems, evolution finds the same solution independently.
