Fossils found in Australia have revealed that giant sea scorpions, known as eurypterids, were powerful swimmers capable of crossing vast ocean distances.
These creatures, which existed over 400 million years ago, were apex predators, reaching sizes larger than humans and wielding impressive claws.
This discovery is exciting because it shows that these ancient arthropods were even more capable than we previously thought.
However, the sudden extinction of sea scorpions after the early Devonian period remains a scientific puzzle, with scientists still seeking the cause of their demise.
