Lumbricina is the scientific name for an earthworm. Earthworms are probably the most common known worms for Americans because the majority of these herbivores are found in North America. They can be found often in gardens and can be used as bait for fishing. They usually range in sizes of about 7 to 8 centimeters, but can be up to 14in. long!
Its segmented body contains a mouth at the first segment and an anus at the last segment. One of the most important features of its body are setae or small bristles that aid their movement and burrowing through dirt. These worms are extremely important for helping plants grow. They eat the nutrients and decomposing organic material from the bottom of the soil and bring it to the top of the soil when they release their waste.
