Worms vary in size from microscopic to over 1 metre (3.3 ft) in length for marine polychaete worms (bristle worms); 6.7 metres (22 ft) for the African giant earthworm, Microchaetus rappi; and 58 metres (190 ft) for the marine nemertean worm (bootlace worm), Lineus longissimus.
Earthworm Segements and Burrowing
Typically only a few inches in length, some members of this species have been known to grow to a serpentine 14 inches. Earthworms' bodies are made up of ring-like segments called annuli. These segments are covered in setae, or small bristles, which the worm uses to move and burrow.
Symptoms of threadworms
In some cases, you may spot threadworms on your bed clothes or sheets at night, or you may notice them in your stools. The worms look like threads of white cotton and are about 1 centimetre long.
dwarf tapeworms — these are 2-4 cm long and 1 mm wide. whipworms — adult worms are around 4 cm in length, with one end that is broad and the other thin, making them look like a whip.
Once they're back in the intestines, the parasites grow into male or female worms. Female worms can be more than 15 inches (40 centimeters) long and a little less than a quarter inch (6 millimeters) in diameter. Male worms are generally smaller.
What is cysticercosis? Cysticercosis is an infection caused by the larvae of the parasite Taenia solium. This infection occurs after a person swallows tapeworm eggs. The larvae get into tissues such as muscle and brain, and form cysts there (these are called cysticerci).
Rope worms are long, rope-like structures that sometimes occur in the intestines. According to some scientists, they are parasitic worms, but it is more likely that they are nothing more than a buildup of intestinal mucus and other debris.
Threadworms live about 5-6 weeks in the gut, and then die. However, before they die the female worms lay tiny eggs around the anus. This tends to be at night when you are warm and still in bed. The eggs are too small to see, but cause an itch around the anus.
Sometimes worms are visible in the anal area, on underwear, or in the toilet. In stool, they look like small pieces of white cotton thread.
Pinworms, also called threadworms, are parasitic worms that live in the intestines and rectums of infected people. Pinworms are small and thin (about ¼ inch to ½ inch long), and white or light gray.
Threadworm begins with an itchy feeling around the anus (back passage), usually at night under warm sheets. Without treatment, threadworm may give rise to vaginitis (inflammation of the vagina) in girls and women. You can often see threadworms, a 1cm thread-like worm, wriggling in your child's stools or their bottom.
Official answer. Yes, it is normal to see dead threadworms in the persons bowel motions. Depending on the frequency of bathroom visits this can take up to one week. Symptoms of threadworm infection usually disappear within one week of treatment.
It moves. If it doesn't wiggle, it's probably lint or a thread. The worm may be seen around the anus or on the child's bottom. It is especially active at night or early morning.
But the title of the world's largest earthworm species goes to Australia's Giant Gippsland earthworm (Megascolides australis), which is about six feet long.
The gigantic worm species, called Websteroprion armstrongi, lived in the sea. But what it fed on is uncertain. Considering its jaws, researchers believe that it may have been both a predator and a scavenger. An interesting aspect of the finding is that it shows that gigantism existed as early as 400 million years ago.
If an earthworm is split in two, it will not become two new worms. The head of the worm may survive and regenerate its tail if the animal is cut behind the clitellum, according to The Washington Post.
Any worms in your gut will eventually pass out in your poo. You may not notice this. To avoid becoming infected again or infecting others, it's very important during the weeks after starting treatment to wash your hands: after going to the toilet.
About half the world's population (over 3 billion people) are in infected with at least one of the three worms forming what Columbia University parasitologist Dickson Despommier calls the "unholy trinity"—large roundworm, hookworm and whipworm.
Pinworms are also called “threadworms.” They're the most common type of intestinal worm infection in the U.S., and one of the most common in the world. They're thin and white, and about one-quarter to one-half inch long -- about as long as a staple. Tapeworms are flatworms that look a bit like ribbons.
Worms are mainly spread in small bits of poo from people with a worm infection. Some are caught from food. You can get infected by: touching objects or surfaces with worm eggs on them – if someone with worms doesn't wash their hands.
Common symptoms of intestinal worms are: abdominal pain. diarrhea, nausea, or vomiting. gas and bloating.
White stool isn't normal and should be evaluated promptly by a doctor. White or clay-like stool is caused by a lack of bile, which may indicate a serious underlying problem. Bile is a digestive fluid produced by the liver and stored in the gallbladder.
This buildup of mucus, which is sometimes referred to as mucoid plaque, actually closely resembles what others believe is the “rope worm.”
Steatorrhea means there's too much fat in your stool (poop). It's a symptom of fat malabsorption. That means your digestive system is having trouble breaking down and absorbing fats.
