Nightcrawlers are large earthworms that usually grow between 4 and 8 inches in length but can be as long as 14 inches. These worms are a reddish-brown color and get their name from the fact they can often be found feeding above ground at night. Nightcrawlers are also known as common earthworms.
While usually found close to the surface of the soil in which they live, nightcrawlers are capable of burrowing up to 6.5 feet down.
Nightcrawlers have mouths on the first segments of their bodies. As they burrow, they extract nutrients from the decomposed leaves and roots in the soil.
Nightcrawlers can live up to 6 years old on average.
Nightcrawlers can eat up to a third of their body weight each day. They are important for the health of ecosystems as they transport nutrients from below ground to the surface.
