Canadian Night Crawler
Nightcrawlers are generally red, brown or gray in color. The head is generally darker than the “flat” tail of nightcrawlers. Their long bodies are covered with annuli, or round segments. Setae, or small bristles, cover the segments of the body and help the nightcrawler move and dig into the ground, reaching depths of 6 feet. Mucus covers the nightcrawler's skin and allows dissolved oxygen to enter its bloodstream.
