Earthworms

As opposed to earthworms, arthropods (crayfish) segments often become fused. Therefore, certain parts of a crayfish that looks like one piece, was once multiple pieces before they became fused together, so some segments were actually once more than just that one segment. An earthworm on the other hand, is just as many segments as are seen, and always has been.

you had them on your body and washed the off

Food such as soil enters the earthworm's mouth where it is swallowed by the pharynx.

aortic arches is another term for heart, and an earthworm has 5.

Prevents the worm form dessication (drying out).

Earthworms are in the Phyllum Annelida, the segmented worms. The earthworm body looks like a long string of checkers, arranged flat-side to flat-side. The roundworns, Nemahelminthes, are not segmented and are shaped like a knitting needle.

The band is called a citellum. It is where the reproductive organs are located.

Easy. Brown, slimy, and ugly. In my garden!

The three animals that feed on worms are birds, lizards, and frogs.

they just see another earthworm with a clitellum and instinctively mate

Earthworms or any other worms are unique in biology in that they have absolutely no skeletal structure whatsoever. A worm uses it's body to move. There is no muscle coordination, and it simply uses a stretching maneuver, similar to snails and slugs. also called Hydrostatic skeleton

Are battalions of bugs harvesting your house, feasting on your fabrics or gobbling your garden? When left alone, ants, aphids, termites and other bothersome bugs can wreak havoc. So here is the question: How do you get the bugs out--and keep them out? Generally speaking, opt for the least toxic method that will solve the problem. Considering that the more effective and powerful insecticides can be dangerous and their long-term effects to our bodies and environment are unknown, prudent avoidance is the best policy. Also, most chemical pesticides wipe out the good, the bad and the ugly bugs, which may ultimately cause some types of infestation problems to worsen. Here are a few helpful steps you can take: Caulk and seal. Your first line of defense against bugs in your house should be to block access routes. Armed with a caulking gun, seal up cracks and crannies where bugs might enter, including openings around pipes and heating ducts. Also weather-strip doors and windows. Fix and clean. Eliminate areas that encourage or foster termites and other insects, especially damp areas or places where drainage is poor. Repair any rotted wood. Be sure no parts of your house are in direct contact with the ground. Clean up and clear out areas that provide safe harbor for insects. Store food, liquids and garbage in sealed containers. Look for problems. Early detection can be half the battle. Most insects increase their numbers very quickly; obviously, getting them before they multiply lessens the needed actions and potential damage. If you suspect that termites or other house-eating bugs may be present in you home, don't wait for the problem to get worse. Though some termites take years to damage a house, others notably Formosan termites can devour tremendous amounts of wood in a matter of months. Professional inspection. With termites, your best bet is to call a pest inspector. Detecting the location and extent of termites and other bugs within the structure of a house is something of an art. Inspectors use a combination of probing, tapping, listening, and looking. Some may use fiber optic scopes that can peer inside a wall. Some even use dogs that can sniff out the presence of termites inside walls. After finding insect infestation, a good inspector will recommend one or more options for eradicating the bugs, and discuss the pros and cons of each. If you've caught the problem early, the solution may be relatively simple and inexpensive. Boric acid, a powder that's relatively safe to use indoors, will treat small, localized infestations of ants, silverfish, firebrats, fleas and cockroaches. Be sure to follow the label directions precisely. Chlorpyrifos, a chemical pesticide that's available in powdered (as well as liquid) form, will kill carpenter ants, powderpost beetles, carpet beetles and a variety of other insects listed on the label. A strong spray from a hose may be enough to dislodge aphids, whiteflies, mites or other plant-sucking insects. Insect soap spray, commercially-available, penetrates the waxy covering on many plant-sucking insects, suffocating them or attacking their nervous systems. Make your own by mixing 3 to 6 tablespoons of dishwashing soap with 1 gallon of water, but test for damage on part of a plant. Organic pesticides are necessary for killing stubborn infestations of plant-sucking insects or heartier plant chewers such as beetles or caterpillars. Deadly to bugs but considered safe for humans, these are not quite as effective or long-lasting as chemical pesticides; but they're safer to use. They generally must be re-applied every 7 to 10 days. Most of these are plant extracts deadly to bugs. The category includes pyrethrum, rotenone, sabadilla, BT (bacillus thuringiensis), neem and horticultural oils. Chemical pesticides are deeper into the hit list for plant, bug they're more powerful and longer lasting. The first choice in this category would be systemics that treat from the ground up (but don't use them around children or pets). The least toxic chemical pesticides are generally considered to include malathion, chlorpyrifos, diazinon and carbaryl (Sevin). Carbaryl will kill honeybees, so be careful with it.

Yeah, that's right. Setae are tiny bristles which cover the wormy and they help wormy to grip the soil that it passes through. Thus, they can make a quick escape easily and also, they can find the right decaying matter (which they use as food) quickly. That's because if wormy grips the soil as it passes it won't slip around. So it can move in any direction happily.

you know when an earthworm is dead when you jab at a couple of times with a stick and it starts to curl up. and then it stops moving. if you r sure that the worm is not dead, pour salt over it and that will always kill it.

No a worm is more complex than a jellyfish

Salamanders can eat just about any small creature such as; crickets,mealworms,earthworms,flys,small shrimp,Etc. Remember they are carnivorious, but they wont bit you. DO NOT FEED Salamanders Freeze Dried Crickets or any other thing that is freeze dried! they should be fed SEVERAL times a week. Rotate the type of insect you feed your salamander every time you feed it so it does not get bored w/ its food.

No, they only have a ventral blood vessel.

Earthworms play an important role in the creation of healthy, productive "living" soils. Without them, we couldn't eat vegetables and fruits!! Or even breathe! Because they help trees!

The early ancestors of the earthworms were partly responsible for ending the global ice age billions of years ago. The relentless burrowing deep in the ocean floor, where the wastes & fossils of organisms accumulated within the sediments, spawned the recycling of carbon nutrients and the formation of carbon dioxide gas. The collective release of CO2 into the Earth's atmosphere generated a greenhouse effect which inevitably warmed the planet to habitable temperatures for later descendants.

An earthworm - (arethari Wormitus) has a different number of stomachs depending on its age, gender and size. For instance a long, male worm aged 20 years or more will have on average, 28 stomachs. However a young, female worm sized 3 inch or less will most defiantly have only 1 stomach.

Earth worms eat rotting vegetation leaves etc found on/in the soil. They also eat small particles of soil. Earthworms are decomposers. They are very beneficial to soils, they help to incorporate organic material into the soil and their faeces or cast help as fertilizer.

Underground.

An earthworm is not a filter feeder. Marine animals that feed by passing nutrient-rich water through their gills are called filter feeders because their gills filter nutrients from the water and pass them into their intestines. An earthworm does not have gills and does not normally live in water. The earthworm's digestive system consists of a pharynx, esophagus, crop (food receptacle), gizzard (used for grinding swallowed earth), and a long, straight intestine.

it helps soil. the soil will be a lot more healthyer and have noutrients

no you can cut it and they will become two.
