Armored Spiky Worm Had 30 Legs, Will Haunt Your Nightmares

A spiky, wormlike creature with 30 legs — 18 clawed rear legs and 12 featherlike front legs that likely helped it filter food from the water — once lived in the ancient oceans of the early Cambrian period, about 518 million years ago, a new study finds.

The critter is one of the first known animals on Earth to develop protective armor and to sport specialized limbs that likely helped it catch food, the researchers said. This newfound species lived during the Cambrian explosion, a time of rapid evolutionary development, they said.

“It’s a bit of a large animal for this time period,” said one of the study’s lead researchers, Javier Ortega-Hernández, a research fellow in paleobiology at the University of Cambridge. “The largest specimen is just under 10 centimeters [4 inches], which, for a wormy thing, is quite mighty.” [See Images of the Spiky Worm & Other Cambrian Creatures]
