An example of annelids are earthworms. They are segmented worms, and is the segments and what separates them (septa) that are largely responsible for locomotion. Movement occurs through a series of constriction and relaxation of the muscles along the worm. This is called peristalsis, and is how food travels down the esophagus after you swallow your food.
In addition to peristalsis, some worms have "hairs" (called chetae) along their bodies. They provide traction for the worm's body which is required for the worm to move. They can also be used to grip onto the soil if a predator such as a bird attempts to pluck it out of the ground.
Nerve-activated muscles are how nematodes move.
Specifically, the roundworm in question (Nematodaphylum) has a cuticle-covered epidermis (skin) over muscles controlling movement. The muscles lie lengthwise, not widthwise. The back's dorsal nerve and the belly's ventral nerve will activate the muscles when the nematode needs to effect thrashing locomotions while lying on one side.
Annelids like any other worm crawl and slither there way.
They don't have to as it is all around them, blood is everywhere in the intestinal lining.
Setae are little bristles attached to segments of annelids. It helps them move.
yes. they are Eucoelomates.
they reproduce asexuallyXD
Annelids are a very diverse group some produce tubes for protection but these are not shells in the strictest sense of the word.
annelids
Yes, most annelids have external bristles called setae. Animals like earthworms use them to help them move.
Annelids have an anus
Probably to make movement easier and/or quicker. Earthworms use it today to move easier through soil.
the annelids also known as annalidia live in damp and tree waste areas so that they can keep their skin moist so that they can move
Setae are little bristles attached to segments of annelids. It helps them move.
annelids
Are annelids vertebrate
Leeches are the class of annelids that has suckers. They use these to suck the blood out of humans and animals in order for them to survive.
Annelids are segmented worms, such as earthworms or nightcrawlers.
Yes, Annelids are invertebrate animals .
Yes, Annelids have bilateral symmetry.
No,human do not use skin as respiratory organ.Some Amphibians, some annelids use skin.
