The larger species, the European nightcrawler is much sought after for fishing bait as it tolerates near freezing water and is one of the few earthworms suitable for salt-water fishing. These worms can grow up to 7 inches (18 cm) in length, but usually are between 3 and 4 inches (7–10 cm) long. Worm farmers also offer other worm species for bait, depending on availability, which usually depends on the prevalent climatic conditions.[2]
