Crawlmine

From Wikitroid, the Metroid wiki

A Crawlmine is basically a crawling mine. It is made by Space Pirates. It is often found in large groups. They are found on the GFS Olympus and Norion when they are under attack as well as the Space Pirate Homeworld. Samus can't lock on to one. Touching a Crawlmine will do damage to Samus.
