Roundworms are small organisms that can live in your intestine, which is part of your digestive system. Roundworms can live in the human intestine for a long time. They can be harmful and cause many problems, including abdominal (belly) pain, fever and diarrhea.
The tongue-eating sea louse - Cymothoa exigua
The only known parasite that not only feeds on one of its host's body parts, but also entirely replaces the very thing it's eaten. This gruesome sea louse makes its home inside a fish's mouth. There it feeds on blood from the tongue until the organ withers away.
Theileria parasites are considered as the smartest among the apicomplexan group for their ability to manipulate the host cells.
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).
Ghost Worms were large, snake like worms that lived in the Caves of Doom on Planet Doom and always moved together in groups. Like many ghosts, they were under the command of Prime Evil.
But animals with simple nervous systems, like lobsters, snails and worms, do not have the ability to process emotional information and therefore do not experience suffering, say most researchers. "There are two types of animals, invertebrates and vertebrates," said Craig W.
Blackworms are considered harmless to humans.
About threadworms
Threadworms, also known as pinworms, are tiny parasitic worms that infect the large intestine of humans. Threadworms are a common type of worm infection in the UK, particularly in children under the age of 10. The worms are white and look like small pieces of thread.
Some species can release a stinging substance. Earthworms and red wriggler worms are perfectly safe to hold bare-handed, though it's probably prudent to wash your hands before eating your next meal.
If an annelid is cut in two, they can regenerate to some degree, and in some species you can even end up with two worms. The common earthworm, however, will only regenerate from the tail end; the head end always dies.
Almost all worms can regrow their tails if they are amputated, and many earthworms can lose several segments from their head end and they will grow back, the Washington Post reports. For some worms, however, the more segments that are cut off, the less likely they are to be fully regenerated.
Invertebrates cover a range of creatures from insects and spiders to mollusks and crustaceans. Farstad said most invertebrates, including lobsters and crabs boiled alive, do not feel pain because, unlike mammals, they do not have a big brain to read the signals.
The consensus among researchers such as Shuker and author Richard Freeman is that the Mongolian Death Worm likely does not exist, and the belief is instead based upon sightings of either a type of limbless reptile known as worm lizard (which resembles a large worm, burrows underground and can reach several feet in ...
Zombie worms don't crave brains: instead they seek bones. The 1 to 3 inch (2 to 7 centimeter) Osedax worms were first discovered living in the bones of a rotting gray whale on the deep sea floor, nearly 10,000 feet (3,000 meters) deep, in 2002.
Earthworms do not have any eyes, ears, teeth or lungs. Don't be fooled though, they make up for it with the interesting aspects they do have. Like five hearts that squeeze two blood vessels to push blood throughout their little bodies.
No need to worry, all the red worms will be killed & digested with the acid present in your stomach.
No, not really. Instead, they have cells called receptors that can sense whether it's light or dark. This allows worms to tell if they're underground or above ground.
Nonpathogenic intestinal protozoa are single-celled parasites commonly found in the intestinal tract but never associated with illness. They do not harm the body, even in people with weak immune systems.
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.
Oldest known parasite is a worm-like animal from 512 million years ago | New Scientist.
(Learn more about creating a worm composting bin.) Earthworms are hermaphrodites, meaning an individual worm has both male and female reproductive organs. Earthworm mating typically occurs after it has rained and the ground is wet. They emerge from the soil and jut out their anterior end.
