Centipedes

The space is called the coelum, and provides cushioning of the digestive system in earthworms and some other simple animals. It allows the organs to function independently of the external structures.

Segmented worms are called annelids because their bodies are made up of a series of repeating segments. The term "annelid" comes from the Latin word "annellus," which means "little ring" or "segment." This segmented body allows annelids to move and flex more effectively.

Leeches have very limited defensive capacities. When they attach themselves to some other creature, they do so in a place where that creature may not notice or may not be able to reach them. And while swimming freely, they can swim away if necessary - but they do not have very high intelligence, so they won't necessarily be able to identify a threat. Like many primitive organisms, they reproduce rapidly and the species can survive even if there is a high death rate due to predation.

Cnidarians do not have a true coelom (body cavity lined with mesoderm). Instead, they have a simple body plan with a central digestive cavity called the gastrovascular cavity. This cavity serves for both digestion and circulation of nutrients.

I am in 7th grade and we are learning about segmented worms.

i got this information from my textbook.

Worms have a tube like body with a bristle like structure called setae. Setae help keep worms in the soil and help them move. Segmented worms also have bilateral symmetry, a body cavity that holds the organs, and two openings -- mouth and an anus.

Asexual and Sexual Flatworms which divide into two then regenerate is asexual Sexual reproduction involves the production of the new cells by the fusion of sex cells to produce a gentically different cell

A 12 inch long segmented worm in humans is likely a tapeworm. Tapeworm infections can occur by consuming contaminated water or food, such as undercooked meat or fish. Symptoms can include abdominal pain, weight loss, and nausea. Treatment typically involves medication to eliminate the parasite.

No, planaria are a type of flatworm and are not considered a bacteria. But, planaria are good for the ecosystem- so maybe it would be like a good type of bacteria that contributes to the functioning of the human body as it the planaria would fo the Earth. You sould really look up planaria, there are pictures and more.

Leeches primarily feed on the blood of other animals, including other leeches. While it is not common for leeches to feed on each other, it can happen if they are in close proximity and there is no other food source available.

No, not all roundworms are parasitic. While some roundworms are parasitic and can cause infections in animals and humans, there are also free-living roundworm species that live in various environments such as soil, freshwater, and marine habitats.

The cuff-like structure in earthworms used in reproduction is known as the clitellum. During mating, the clitellum secretes a mucus that forms a cocoon around the eggs and sperm, eventually developing into a fertilized egg. This cocoon is then deposited in the soil, where the new earthworms will hatch.

Because there's no source of food where they live in the Hadal zone (the deepest darkest trenches of the ocean) so they need bacteria to turn toxic chemicals streaming out of hydrothermal vents into "food" (chemicals they can use to survive).

Segmented worms, also known as annelids, are commonly found in a variety of habitats such as marine environments, freshwater bodies like lakes and rivers, and terrestrial environments like soil. They can also be found in damp locations like forests, compost piles, and even in sediments at the bottom of bodies of water.

Segmented worms, such as earthworms, can be sensitive to changes in temperature. They may move to deeper soil layers to avoid extreme temperatures or enter a state of dormancy in harsh conditions. In some cases, temperature changes can affect their metabolic rate and reproductive behaviors.

Yes, segmented worms are cold-blooded animals, which means that their body temperature is dependent on the temperature of their environment. They regulate their internal temperature by moving to warmer or cooler areas as needed.

There is no specific scientific name, there is only a Greek root word.

The shiny lining of the coelom in a perch fish is called the peritoneum. It is a thin membrane that lines the body cavity and provides protection for the internal organs.

Segmented worms, lets just use an earthworm as an example, prefer moist, not wet, comditions. If you want to keep one, this is what I suggest. I have kept many, many worms in order to entertain children, and sometimes myself, and have done quite an amount of research. Find a tall glass jar if it is for entertaining, if it is a project it works well too. If you cannot find one, a plastic bin or other container will work. Find some leaves, you may pick them off trees or off the ground, and put them in the jar. Then fill the jar with about four or so inches of either "wild" dirt, or dirt you got from a bag. Any dirt works well, as long as it has no mold. Besides otherwise beleifs, segmented worms eat decaying plants for nutrition, not dirt. After that step, you may put in more leaves if you wish, but it is not required. Put in a little less than an inch of sand, then three more inches of dirt. Finnaly, put a few leaves in water for about half an hour or until sort of mushy like. Put it in as a "topping" in the jar, and release the worms into to jar. Remember to put more leaves in the jar regularly, and spray the dirt with a spray bottle about ten times every day to keep the soil moist. There are no other very important needs, and plants are not required. I hope this helped. And to let you know, worms do not eat plants, just the decaying leaves. i suggest you put worms in plant pots with you plants. They will loosen the soil, making it easier for the roots to grow, and they will eat any dead leaves, and the leaves will decompose more quickly. I do hope you have fun with your worm farm.

Planarian worms have the ability to regenerate into two new worms if cut in half because of their amazing regenerative capabilities. Each half is able to regenerate the missing parts, resulting in two separate worms.

fast running rivers! there so many leeches there!

Class:Chilopoda

Segmented worms, or earthworms, reproduce through cross-fertilization. They form a mating pair where each individual exchanges sperm with the other. The fertilized eggs are enclosed in a protective cocoon that is deposited in the soil.

Roundworms are multicellular organisms that possess longitudinal muscles and a complete digestive tract, with a mouth and an anus. Their body plan is characterized by a single body cavity that houses their organs, including their nervous and reproductive systems.
