simple animals have this total regeneration ability, even more, if you cut an earth worm to several pieces, each can regenerate to a complete worm.\nthis is very typical of plants.\nmore advanced/complicated animals have a much smaller regenerative ability. something in the genes of the primitive earth worms is lost among the more advanced animals.

It's impossible to identify the worm from that description.  There are a number of options.\n\nHowever, my best guess is that it is a horsehair worm.  Horsehair worms are rather fascinating creatures, possibly responsible for inspiring the film "Alien".  Adult worms live in water where they lay their eggs.  The eggs hatch into larvae, who make their way to an appropriate place to be eaten!  Once an insect (usually a grasshopper or a relative, such as cockroaches) eats them, they crawl out of it's digestive system and live in it's abdomen, growing every larger.  When they become adults, they secrete a chemical, causing the insect to get very thirsty.  It rushes to the nearest body of water, where the horsehair worm tears it's way out of the insects stomach and into the water, where it looks for another horsehair worm so it can start the whole process over again.

it is a system that comprises of the kidneys ,ureterand urethra where the function of this system is to collect the nitrogenous and other kind of harmful wastes and eliminate it from the body .this system also contains the sweat glands and the lungs as they eliminate the the wastes,regulate the temp of our body and release the harmful co2 from our body respectively .kidney forms stores and then eliminates the waste as urine from the body

A storage organ is a part of a plant specifically modified for storage of energy (generally in the form of carbohydrates) or water. Storage organs often grow underground, where they are better protected from attack by herbivores. Underground storage organs and the plants that bear them are sometimes called geophytes.

water vascular system helps the echinoderms in circulating the food & waste materials.....moreover it helps in their locomotion....

if your keeping one as a pet they'll eat crickets, wax worms, and meal worms, although you dont want to give them wax worms more than twice a week b/c they have a lot of fat in them, and if you give them meal worms you have to crush the heads first b/c the meal worms hard outershell meens its still alive in the frogs stomache and can chew at or through the stomach lining.  i immagen silk worms would also be good if you could get a hold of them

worms like to come to the surface when its wet , not because they are drowning, but because its moist and they find mates.  Earth worms are hermaphrodites, and they lines up with each other with lots of slime and fertiliz each other.Once they are done they go back down burrows and deposit egg sac.

An earthworm has 5 hearts, and it has a closed circulatory system, in which blood is confined to vessels.

Locomotion.  The setae on each segment allow the earthworm to "grip" the earth while their longitutinal and circular muscles contract the rest of the body into place to apply forward pressure to "burrow" through the earth.

Oh well, with that information it's easy to identy. \n\nThe  creature is Biplaium kewense. They are commonly known as "worm killers".  See the link below for some photos\n\nAs others have guessed it is a planarian. Worm killers are an exotic pest species imported from Viet Nam in the soil of potted plants. They are carnivorous and hunt earthworms and small insects. They immobilise their prey by coating them with that slime they secrete and then stick a tube into them and suck their insides out.\n\nBTW, well spotted that it uses it's head like a sensor. That is exactly what they do. There are pits under the head that act like a nose that enables the animal to track earthworms, slugs and other prey animals.

Leeches can help heal skin grafts and restore blood circulation. Their primary function is to drain blood. Pooled blood around a wound can threaten tissue survival.\nLeeches apply the perfect amount of suction to get the blood flowing

The kidneys filter the blood, produce urine, and reabsorb vital electrolytes.  The spleen destroys old blood cells and plays a part in the immune system.

Basically, an earthworm "burrows into and helps aerate soil."\n\nThese links might be able to help you with your question.
