A Nearly Invisible Spider Was Just Filmed for the First Time After Being Discovered in 2024
It measures about 3 millimeters long — roughly the size of a sesame seed — and until recently, no one had ever seen it move. Now, a newly discovered species of ground spider has been filmed for the first time, giving scientists and the public their earliest glimpse of this minuscule creature in action.
The species, named Cryptodrassus michaeli, was officially described in 2024 by scientists in Spain. Footage of the spider was released in April 2026 by the Associated Press, marking the first video documentation of the species’ behavior.
This Tiny Spider Was Found in a Remote Spanish Park
Researchers discovered Cryptodrassus michaeli in the Cabo de Gata-Níjar Natural Park in Almería, a semi-arid region in southeast Spain. The park is a striking landscape of semi-arid desert, coastal areas and volcanic formations — and apparently, it is also home to spiders that had gone entirely unnoticed until now.
The species was one of three new spiders identified during field surveys in the area, alongside Echemus almeriensis and Zelotes imazigheni.
Jordi Moya-Laraño, a research scientist at the Spanish Research Council, told the Associated Press: “It is a new species and the particularity of this species is that it is very tiny compared to others in their family.”
That family is Gnaphosidae, a group of ground spiders that includes approximately 2,500 species. Cryptodrassus michaeli stands out in the group for its remarkably small size.
What the Video of the Tiny Spider Shows
The AP video shows the spider moving across the ground, offering scientists their first visual documentation of its behavior. With brown and black coloration, the spider blends almost seamlessly into soil and leaf litter — which may help explain why it avoided detection for so long.
Capturing the footage was no simple task. Researchers obtained the video through fieldwork that involved searching through leaf litter, overturning rocks and studying specimens in laboratory conditions. For a spider this small and this well camouflaged, even finding one requires patience and careful effort.
A Spider Species Still Full of Mysteries
Despite the breakthrough of filming Cryptodrassus michaeli, scientists report that little is currently known about the species, including its diet, population size and reproductive behavior. Those are significant gaps, and researchers have much more work ahead before they fully understand how this spider lives and what role it plays in its habitat.
What is known about ground spiders more broadly may offer some clues. Ground spiders are typically nocturnal and range from small to medium in size, often covered in dark, velvety hair. They are ground dwellers rather than web builders, hunting prey along the forest floor and in the debris that accumulates there.
Why Discovering New Species Still Matters
The identification of Cryptodrassus michaeli arrives at a time when researchers are increasingly focused on documenting biodiversity before it disappears. Scientists are studying the ecosystems of Cabo de Gata-Níjar Natural Park as climate change poses risks to the region’s biodiversity, including the possibility that species may become extinct before they are fully documented.
Spiders play a role in maintaining ecosystem balance, making their identification and study important for understanding environmental changes. A species that vanishes before it is ever recorded is a loss not just for science but for the broader health of the ecosystems it inhabits.
For now, a 3-millimeter spider from a remote corner of Spain has earned a place in the scientific record — and on video. What researchers learn next about Cryptodrassus michaeli could reveal even more about the hidden diversity living just beneath our feet.
