Evidence of a "walking cactus" has been found in China.
The fossils of an ancient, spiny creature with a worm-like body and and ten pairs of armored and likely jointed legs were found during an excavation in southwestern China's Yunnan Province.
Study leader Jianni Liu said: "I was really surprised. I said, 'What's that strange guy with the soft body with very strong legs?'"
Although the newfound animal is a lobopodian - a primitive group of creatures that flourished in the Cambrian seas - it looks more like a modern arthropod -joint-limbed animals such as spiders and crustaceans.
Therefore its existence strengthens the theory that modern arthropods evolved from lobopodians.
