Did you ever find the worm that drew on your hand again?

I’d like to think that it’s still out there, working away in my garden. Maybe I have seen it, but not recognized it without its pencil. Or maybe it’s too smart to get caught again…

Favourite worm species?

i dont have any specific species in mind per se but im a fan of anything coming from orders tricladida (flatworms), polycladida (marine flatworms) and haplotaxida (earth worms, generally). - mod wiggles

If anyone wants an actual answer, here's the family tree for worms, using Earthworms as an example since they're probably the ones most people are thinking about:

Animals Kingdom Animalia

Segmented Worms Phylum Annelida

Clitellates Class Clitellata

Earthworms and Allies Subclass Oligochaeta

Order Haplotaxida

Earthworms Family Lumbricidae

And then meanwhile, here's the family tree for insects:

Animals Kingdom Animalia

Arthropods Phylum Arthropoda

Hexapods Subphylum Hexapoda

Insects Class Insecta

So no, worms are not bugs, the last thing they have in common is that they are in the Kingdom Animalia, aka, they're animals.

There are three Kingdoms: Animalia, Plantae, and Fungi. Animals, plants, and mushrooms. Insects and worms are both animals, but besides that, they aren't related.

Earthworm

"The Earthworm" and "Nightcrawlers" redirect here. For other uses, see Earthworm (disambiguation) and Nightcrawlers (disambiguation). An earthworm is a tube-shaped, segmented worm found in the phylum Annelida. Earthworms are commonly found living in soil, feeding on live and dead organic matter. An earthworm's digestive system runs through the length of its body. It conducts respiration through its skin. It has a double transport system composed of coelomic fluid that moves within the fluid-filled coelom and a simple, closed blood circulatory system. It has a central and a peripheral nervous system. The central nervous system consists of two ganglia above the mouth, one on either side, connected to a nerve cord running back along its length to motor neurons and sensory cells in each segment. Large numbers of chemoreceptors are concentrated near its mouth. Circumferential and longitudinal muscles on the periphery of each segment enable the worm to move. Similar sets of muscles line the gut, and their actions move the digesting food toward the worm's anus. Earthworms are hermaphrodites—each individual carries both male and female sex organs. They lack either an internal skeleton or exoskeleton, but maintain their structure with fluid-filled coelom chambers that function as a hydrostatic skeleton. "Earthworm" is the common name for the largest members of Oligochaeta (which is either a class or a subclass depending on the author). In classical systems, they were placed in the order Opisthopora, on the basis of the male pores opening posterior to the female pores, though the internal male segments are anterior to the female. Theoretical cladistic studies have placed them, instead, in the suborder Lumbricina of the order Haplotaxida, but this may again soon change. Folk names for the earthworm include "dew-worm", "rainworm", "night crawler", and "angleworm" (due to its use as fishing bait). Larger terrestrial earthworms are also called megadriles (literally, "big worms"), as opposed to the microdriles ("small worms") in the semiaquatic families Tubificidae, Lumbricidae, and Enchytraeidae, among others. The megadriles are characterized by having a distinct clitellum (which is more extensive than that of microdriles) and a vascular system with true capillaries. Earthworms are far less abundant in disturbed environments and are typically active only if water is present. More details Android, Windows

Common Earthworm Classification (Taxonomy) and Characteristics

I doubt whether there are many other animals which have played so important a part in the history of the world, as have these lowly organized creatures. -Charles Darwin on the importance of earthworms. The earthworm plays a major role in the proper functioning of the ecosystem of the soil. It acts as a scavenger, and helps in the recycling of the dead and decayed plant matter by feeding on it. It increases the soil fertility and is often referred to as a farmer's friend. It burrows the soil and ingests soil particles coming in its way. Both these processes aerate the soil and help in the inter-mixing of the soil particles of the upper and underlying layers. Earthworms are found all over the world in any type of soil, except the waterlogged and sandy areas. Let's discuss in brief about the taxonomic classification and characteristics of earthworms. Taxonomy of the Common Earthworms

Though all species of earthworm are classified in the same class and order, they do not belong to the same family. Following is the classification of the common earthworm (Lumbricus terrestris). Kingdom: Animalia Earthworms are eukaryotic (cells have nuclei), multicellular organisms. They have the ability to move and depend on dead plant materials and microorganisms for food. Phylum: Annelida Earthworms belong to the phylum annelida which comprises segmented worms. The segments of the earthworm's body, known as annuli, are separated by transverse dividing walls known a septa. They have multiple segments, with those belonging to a species possess organs in same segments. In some species of annelids, septa are less defined or even absent.

Class: Clitellata Earthworms have clitellum, a type of collar that secretes clitella or cocoon during reproduction. The head of earthworm is less developed than other annelid species. Subclass: Oligochaeta Earthworms have setae or bristles on the body, which helps them to attach to the surface during movement. They lack lateral appendages or parapodia, which is a characteristic feature of the subclass polychaeta. Order: Haplotaxida The common earthworm is categorized under Haplotaxida, which is one of the two orders of Oligochaeta. Family: Lumbricidae The common earthworm belongs to Lumbricidae which is one of the largest earthworm family. About 33 species of earthworms are identified under this family. Genus: Lumbricus Species: terrestris Characteristics of the Common Earthworm The common earthworm (Lumbricus terrestris) resembles a cylindrical tube, with an average length of about 7 cm. - 8 cm., with some members of this species even growing to 35 cm. They are found abundantly in North America, Europe and western Asia. The reddish-gray colored body of the earthworm is segmented, and the vital organs are present in particular segments. The skin is covered by a moist mucous layer that serves the main purpose of respiration (exchange of air). An earthworm does not have any locomotory organs and scott nordheimer therefore moves by means of muscle contraction and relaxation. The earthworms are also known as night crawlers because they are usually come above ground during the night. During the day, they burrow the ground using their strong toothless yet muscular mouths. While burrowing, an earthworm feeds on dead plant materials and organic matter present in the soil. The ingested food is broken down into finer particles in its muscular stomach also known as gizzard. The fine food particles are acted upon by various enzymes for digestion process. Useful nutrients are absorbed and undigested soil and other particles are passed out as worm casts. Studies have revealed the presence of useful soil microorganisms in earthworm casts. The earthworms also transfer nutrients and minerals from the earthen layers below, to the surface above through their waste. The small burrows that they create keeps the soil aerated. Thus the earthworms play a vital in maintaining the health of the soil. Earthworms are hermaphrodite, meaning both male and female sex organs are present in the same body. However, reproduction takes place via cross-fertilization. The eggs are enclosed in an egg casing or a cocoon. The juvenile earthworm resembles an adult worm, except that it lacks sex organs. It attains sexual maturity within 2 - 3 months after hatching. One of the characteristic features of many different species of earthworms is their ability to regenerate lost segments of their bodies. The lifespan of the earthworm varies depending upon the species; the common earthworm can live up to 6 years in the wild. Common predators of the earthworm include birds and other small mammals.

Самый большой червяк в мире (5 фото + 1 видео)

Отвратительные животные, которые могут быть как вредными, так и полезными. Речь идет о червяках. Многие, при виде этого ползучего содрогнутся и перекосятся, другие же наоборот, считают этих созданий милыми и даже не брезгуют взять в руки. Дождевые черви относятся к отряду Haplotaxida, подотряду малощетинковых.
