Canadaspis is a bizarre genus of crustacean from the Cambrian Period. Its name means "Shield of Canada." It had a large shield that covered its head.
Canadaspis probably used its legs to crawl along the sea floor. When Canadaspis crawled, its legs made a rippling motion that could have stirred up food or helped it with respiration by stirring up the water.
Canadaspis are commonly found in the Burgess Shale. But Canadaspis is also found in Utah, Nevada, and China.
