Paleontologists in England discovered the existence of a new marine species that roamed the Earth before the dinosaurs and nicknamed the headless arthropod “Sue” after one of their mothers, according ...

The unique features of Mosura fentoni astounded paleontologists. Paleontologists have discovered that a three-eyed sea moth predator lived on Earth half a billion years ago with evidence found in one ...

Scientists have decoded the sea spider’s genome for the first time, revealing how its strangely shaped body—with organs in its legs and barely any abdomen—may be tied to a missing gene. The detailed ...

Discovered 25 years ago, a 444-million-year-old marine arthropod fossil stumped paleontologists, as they couldn’t identify its exact species. Sarah Gabbot, who originally discovered the specimen, ...

What looks like a spider but isn’t one, lives underwater and breathes through its legs? That would be the mysterious sea spider. With over 1,300 species living in every ocean, these marine arthropods ...

Scientists have discovered a bizarre fossilized creature that lived 465 million years ago with the content of its gut still preserved. In a study published in the journal Nature, a team of researchers ...

The special brains of spiders may have started to evolve in the oceans, long before their ancestors crawled onto land. A fresh look at a 500-million-year-old fossil by researchers from the University ...

The spindly-legged creatures, which are not closely related to spiders, defy expectations of fatherhood in the animal kingdom. An Antarctic giant sea spider sits on the ocean floor at Dayton’s Wall, a ...

In a fascinating study published in Current Biology, researchers have turned our understanding of arachnid evolution on its head. For years, scientists assumed that spiders, scorpions, and their kin ...

An international collaboration featuring the University of Vienna and the University of Wisconsin-Madison (USA) has led to the first-ever chromosome-level genome assembly of a sea spider (Pycnogonum ...

Unlike other sea spiders that carry their eggs on their backs, male giant antarctic sea spiders spend two days gluing their eggs to the seafloor. When you purchase through links on our site, we may ...
