The average earthworm is a reddish brown color, with a pointed posterior and anterior end. There are no eyes or other discerning facial features, only a simply opening for a mouth. Earthworms have long, segmented bodies, covered in microscopic setae, or bristles, which help to anchor and pull the worm via longitudinal muscle contractions. Earthworm...
Their sizes vary: they can be between two centimeters and about three meters in length. The biggest known earthworm is the giant Gippsland earthworm, found in Australia. It is usually about 80cm in length, but can grow to about 2 meters. The most common earthworm (in Europe, and most other temperate climate regions) grows to a size of about 20-25 c...
Earthworms are commonly found in soil. They can be found everywhere, except in polar or dry climates. Earthworms typically live in damp (but not wet), loose soil. They can also be found in loose leaf litter, and after it rains they can be found on the surface as they are forced out of the water-logged soil. Many gardeners welcome earthworms, as the...
The typical earthworm diet is decaying matter, leaf litter, microbial fungi, and other microscopic organisms. Earthworms are important to the environment, breaking down organic matter and passing it through their gut as newly enriched soil. An earthworm has no teeth, so it swallows grit to help grind food in its multi-chambered gut. As an earthworm...
Earthworms are hermaphrodites, meaning they each contain male and female gametes. During mating, both worms exchange sperm and have eggs fertilized. The belt-like swollen area on the earthworm’s body, commonly called the "saddle" or "belt", is called a clitelum. It secretes a slimy substance that forms capsules which protect the eggs (sperm cells a...
At birth, earthworms emerge small but fully formed. They only lack sex structures which develop in about 60 to 90 days. They become fully grown in about one year. Scientists predict that the average lifespan under field conditions is four to eight years, while most garden varieties live only one to two years.
Earthworms travel underground thanks to muscular contractions which alternately shorten and lengthen the body. As they burrow, their body secrets lubricating mucus. As a result of their movement through their lubricated tunnels, worms can make gurgling noises underground when disturbed. Earthworms move through soil by expanding crevices with force;...
Earthworms are classified into three main ecophysiological categories: 1. (1) leaf litter- or compost-dwelling worms that are nonburrowing, live at the soil-litter interface and eat decomposing organic matter; 2. (2) topsoil- or subsoil-dwelling worms that feed (on soil), burrow and cast within the soil, creating horizontal burrows in upper 10–30 c...
Earthworms are preyed upon by many species of birds (e.g. robins, starlings, thrushes, gulls, crows), snakes, wood turtles, mammals (e.g. bears, boars, foxes, hedgehogs, pigs, moles) and invertebrates (e.g. ants, flatworms, ground beetles and other beetles, snails, spiders, and slugs). Earthworms have many internal parasites; they can be found in t...
The major benefits of earthworm activities to soil fertility for agriculture can be summarized as: 1. Biological: In many soils, earthworms play a major role in the conversion of large pieces of organic matter into rich humus, thus improving soil fertility. 2. Chemical: In addition to dead organic matter, the earthworm also ingests any other soil p...
