The Giant Gippsland Earthworm is one of the largest earthworms in the world. It grows to 80–100+ cm long and is 2 cm in diameter. It has 300 to 400 body segments.
The longest earthworm is Microchaetus rappi of South Africa. In 1967 a giant specimen measuring 6.7 m (21 ft) in length when naturally extended and 20 mm (0.8 in) in diameter was found on a road between Alice and King William's Town.
These giant earthworms average 1 metre (3.3 ft) long and 2 centimetres (0.79 in) in diameter and can reach 3 metres (9.8 ft) in length; however, their body is able to expand and contract making them appear much larger.
Besides the well-known 'Gippsland Giant', Megascolides australis, cited in the Guinness Book of Records at 3 metres, others also grow large. A species of Digaster found near Kyogle in north-eastern New South Wales, often grows to a length of more than 150 cm and is as thick as a garden hose.
The Giant Gippsland Earthworm Megascolides australis is only found in small areas of South and West Gippsland, Victoria. It is one of the largest earthworms in the world, often exceeding one metre in length. It is rarely seen due to its underground life cycle but sometimes can be heard as it moves beneath the ground.
Found only in a critically endangered ecosystem known as the Palouse prairie, a storied giant was long thought to be extinct. Only a handful of sightings have been reported since the 1970s. Today, there are only 10 of these animals in captivity in the world.
Earthworms are eaten in some areas of the world, including China and the Philippines (IFIS, 2009). Based on their nutrient content, earthworms Eisenia foetida are an excellent source of readily available protein and minerals in human diet and are included in the Dictionary of Food Science and Technology (IFIS, 2009).
What many of us in Canada and the U.S. think as inedible is actually part of daily life in other countries around the world. One of those “delicacies” is the worm. It's called Entomophagy!
Although it had been thought to be extinct in the 1980s, recent evidence has demonstrated that the species is still living. The latest sighting included recovery of two specimens, an adult and a juvenile, which were unearthed on March 27, 2010 by scientists at the University of Idaho including Samuel James.
This happens about 2 months after the egg was swallowed. Adult worms live in the small intestine for 1 to 2 years. They can be as thick as a pencil and can measure from 5 to 14 inches long. A person can have many worms at the same time if many eggs hatch.
The Giant Gippsland Earthworm feeds on roots and organic matter in the soil, although it may occasionally feed on plant material on the surface by poking its head out of the burrows (Taylor et al. 2004; Yen & Van Praagh 1994).
Some worms that people get can grow to be really big --more than 3 feet long. Others are tiny. The worst parasitic worms are usually found in warm tropical or subtropical parts of the world, but some worms are common in other places, too.
Although Australia has over 1000 species of native earthworms, Gippsland is home to possibly the largest and undoubtedly the most famous of all earthworms - the Giant Gippsland Earthworm.
OSLO (Reuters) - Worms squirming on a fishhook feel no pain -- nor do lobsters and crabs cooked in boiling water, a scientific study funded by the Norwegian government has found.
However, earthworms can survive if their tail end is cut off, and can regrow their segments but earthworms generally cannot survive if the front part of their body between the head and the saddle is cut as this is where their major organs are.
Do worms have brains? Yes, although they are not particularly complex. Each worm's brain sits next to its other organs, and connects the nerves from the worm's skin and muscles, controlling how it feels and moves.
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.
In the depths of the ocean, life can extend far beyond its usual limits. Take the tube worm Escarpia laminata: living in an environment with a year-round abundance of food and no predators, individuals seem to live for over 300 years.
Larvae can become adults only inside the human body. The adult worms live between layers of connective tissue (e.g., ligaments, tendons) under the skin and between the thin layers of tissue that cover muscles (fascia).
“Pathogens that we already know can be carried by worms include E. coli O157 and salmonella. These bacteria can cause severe gastrointestinal infections in humans and are commonly found in soil.
She describes the taste as distractingly earthy — which makes sense, as it's dirt that earthworms eat. "In my experience, bugs taste like their diet," she says. "So whatever the bug has been eating, frequently they will taste somewhat like that." The same goes for worms, says Martin.
It reaches somewhere between two to five feet long. [*] The Mongolian Death Worm can kill from a distance by spewing corrosive yellow saliva and generating an electric discharge.
Heartbeats: Worms don't have just one heart. They have FIVE! But their hearts and circulatory system aren't as complicated as ours -- maybe because their blood doesn't have to go to so many body parts. Moving around: Worms have two kinds of muscles beneath their skin.
Giant earthworms are found in several states of Australia and from many countries around the world, including China, Vietnam, South and North America, India and South Africa. Just as fisherman like to exaggerate the size of the fish they catch, there are many exaggerated claims about the size of worms.
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.
