In Binchaun County, China, a snake-like earthworm measuring over 19 inches (a half-meter) long was found in a house gutter. Li Zhiwei, a Forestry Bureau worker, made the discovery and eventually decided to keep the worm and raise it in his backyard. An adult earthworm's measurements vary by species and can range anywhere from 10mm long and 1mm wide, to 3-meters long and over 25mm wide. Environmental factors also influence an earthworm's body size, and they tend to grow longer and larger during humid seasons if they take in sufficient nutrition and have no natural enemies. Biologists plan to study the earthworm found by Li to classify it and identify the reason it was able to grow to its current length.
