They can reach 14 inches in length and 0.39 ounces of weight. Despite that, earthworms require partner for mating with whom they exchange packages of sperm. Earthworms are hermaphrodites, which mean that each earthworm contains both male and female reproductive organs. Why are earthworms important? This capability varies by species. The typical earthworm diet is decaying matter, leaf litter, microbial fungi, and other microscopic organisms. Earthworms sometimes appear to have a "belt" or "saddle" around their bodies; this is a clitelum, a structure containing maturing eggs. How big do earthworms get? It works between layers of the biosphere to take dead matter and turn it into rich living soils full of opportunities. Earthworms can be a farmer's best friend. Earthworms are even consumed as delicacy in certain parts of the world. Worms have both male and female organs, but they still need another worm in order to reproduce. The average earthworm is a reddish brown color, with a pointed posterior and anterior end. Earthworms don't have lungs; instead, they breathe through their skin. Earthworms have no lungs, and absorb oxygen directly through their skin. Earthworms are hermaphroditic, meaning that they play the roles of both males and females when it comes to reproduction. Typically only a few inches (7 or 8 centimeters) long, some members of this species have been known to grow to a snakelike 14 inches (35 centimeters).

The earthworm is an agent of life, of cycles. A few more Earthworms facts. Size of earthworm depends on the species. Photo: crabchick / Foter. It is usually about 80cm in length, but can grow to about 2 meters. Earthworms are beneficial for the soil because they dig tunnels (which facilitate aeration) and transfer nutrients from deeper layers of the ground to the surface. Their behavior can naturally improve the quality of crops. Their bodies are permeable, meaning fluids and air can be absorbed directly into the worms from the environment. Their sizes vary: they can be between two centimeters and about three meters in length. For this reason, they are valued by farmers and gardeners worldwide. A. An earthworm has no teeth, so it swallows grit to help grind food in its multi-chambered gut. Each segment on the body of earthworm contains group of bristles (called setae) which are used for movement. Belt-like swollen area on the earthworm’s body is called clitelum. Animals and Nature; Invertebrates Earthworms have long, segmented bodies, covered in microscopic setae, or bristles, which help to anchor and pull the worm via longitudinal muscle contractions. It is a type of annelid. Earthworms have segmented body that is usually reddish-brown in color. Earthworms are everywhere, even if you can’t see them. Fertile soil can contain up to 432 earthworms per square meter. Afterwards, each earthworm builds a tiny cocoon out of a substance secreted from the bulge in its body, close to its head. Earthworms reach maturity after 10 to 55 weeks and live from 4 to 8 years in the wild. Earthworms feel are slimy to the touch, but they are actually covered in tiny, hair-like bristles called setae. Most earthworms can regrow lost segments, assuming the worm has not had too much damage. In order to do this, they must stay moist, and do so by lubricating their skin with glands along their bodies. They are quite happy in compost, gorging themselves on decaying vegetable matter. These interesting earthworm facts might make you think differently about these squiggly subterranean neighbors. Earthworms do not have skeleton. Earthworms typically live in damp (but not wet), loose soil. During mating, both worms exchange sperm and have eggs fertilized.
