Unlike birds, earthworms do not have stomachs, but they do have crops, which are the places where their food is stored before it is sent to their gizzards. The gizzard works by squeezing food from fine grains of sand or rock.
Do worms eat their own poop?
Yes, worms do eat poop. This includes various animal manures. A good rule of thumb is to know that worms love to eat various fungi, dead and decaying things.

What is parthenogenetic in worms?
Several common earthworm species are mostly parthenogenetic, meaning that growth and development of embryos happens without fertilization . Among lumbricid earthworms, parthenogenesis arose from sexual relatives many times. Parthenogenesis in some Aporrectodea trapezoides lineages arose 6.4 to 1.1 million years ago from sexual ancestors. A few species exhibit pseudogamous parthogenesis, meaning that mating is necessary to stimulate reproduction, even though no male genetic material passes to the offspring.
What is the class of an earthworm?
Annelida. Class: Clitellata. Order: Opisthopora. Suborder: Lumbricina. An earthworm is a terrestrial invertebrate that belongs to the phylum Annelida. They exhibit a tube-within-a-tube body plan, are externally segmented with corresponding internal segmentation, and usually have setae on all segments.
How many pairs of testes does an earthworm have?
Earthworms have one or two pairs of testes contained within sacs. The two or four pairs of seminal vesicles produce, store and release the sperm via the male pores. Ovaries and oviducts in segment 13 release eggs via female pores on segment 14, while sperm is expelled from segment 15.
How big is an earthworm?
Earthworm head. Depending on the species, an adult earthworm can be from 10 mm (0.39 in) long and 1 mm (0.039 in) wide to 3 m (9.8 ft) long and over 25 mm (0.98 in) wide , but the typical Lumbricus terrestris grows to about 360 mm (14 in) long.
What is the blood vessel in an earthworm?
The closed circulatory system has five main blood vessels: the dorsal (top) vessel, which runs above the digestive tract ; the ventral (bottom) vessel, which runs below the digestive tract; the subneural vessel, which runs below the ventral nerve cord; and two lateroneural vessels on either side of the nerve cord.

Benefits of Worm Casting
- Here are 11 key benefits for using worm castings in your garden: 1. Packed with nutrientswhich helps to make plants grow faster 2. All nutrients are water-soluble, making it an immediate plant food 3. Extracts toxins, harmful fungi and bacteria from the soil. This helps prevent plant disease 4. Repels peststhat feed on plants such as aphids and spider mites (a natural pesticide) 5. Cont…
Worm Castings vs. Chemical Fertilizers
- Chemical fertilizers are a quick win solution which help plants grow fast and strong. They contain all the essential nutrients for plant growth. This include nitrogen, potassium and phosphorus. But it also damage soil, increase acidity (lowers pH), encourages plant disease and contaminates ground water. The acids contained in chemical fertilizers destroy soil structure. This makes it m…
How to Use Worm Castings

- So now when someone asks you “what are worm castings”, you can tell them it’s the most incredible poop in the world. The power of worm castings should not be understated, it’s the ultimate organic fertilizer and soil conditioner for your garden. This is one of many reasons why you should start a worm farm.
Overview
An earthworm is a terrestrial invertebrate that belongs to the phylum Annelida. They exhibit a tube-within-a-tube body plan, are externally segmented with corresponding internal segmentation, and usually have setae on all segments. They occur worldwide where soil, water, and temperature allow. Earthworms are commonly found in soil, eating a wide variety of organic matter. This organic m…
Anatomy
Depending on the species, an adult earthworm can be from 10 mm (0.39 in) long and 1 mm (0.039 in) wide to 3 m (9.8 ft) long and over 25 mm (0.98 in) wide, but the typical Lumbricus terrestris grows to about 360 mm (14 in) long. Probably the longest worm on confirmed records is Amynthas mekongianus that extends up to 3 m (10 ft) in the mud along the banks of the 4,350 km (2,703 mi) Mekong …
Life and physiology
At birth, earthworms emerge small but fully formed, lacking only their sex structures which develop in about 60 to 90 days. They attain full size 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.
Several common earthworm species are mostly parthenogenetic, meaning tha…
Taxonomy and distribution
Within the world of taxonomy, the stable 'Classical System' of Michaelsen (1900) and Stephenson (1930) was gradually eroded by the controversy over how to classify earthworms, such that Fender and McKey-Fender (1990) went so far as to say, "The family-level classification of the megascolecid earthworms is in chaos." Over the years, many scientists have developed their own classification systems for earthworms, which led to confusion, and these systems have been an…
Ecology
Earthworms are classified into three main ecophysiological categories: (1) leaf litter- or compost-dwelling worms that are nonburrowing, live at the soil-litter interface and eat decomposing organic matter (epigeic) e.g. Eisenia fetida; (2) topsoil- or subsoil-dwelling worms that feed (on soil), burrow and cast within the soil, creating horizontal burrows in upper 10–30 cm of soil (endogeic); and (3) …
Economic impact
Various species of worms are used in vermiculture, the practice of feeding organic waste to earthworms to decompose food waste. These are usually Eisenia fetida (or its close relative Eisenia andrei) or the Brandling worm, commonly known as the tiger worm or red wiggler. They are distinct from soil-dwelling earthworms. In the tropics, the African nightcrawler Eudrilus eugeniae and …
