Interesting Facts About Worm: Appreciate Nature With Charismatic Video Of Worm In The Rain

Worms are several different distantly related creatures which typically have a lengthy cylindrical tube-like body and without any limbs. Worms differ in size from microscopic to more than one meter (3.3 feet) in length for the marine polychaete worms (bristle worms), 22 feet (6.7 meters) for the African giant earthworm, and 190 feet (58 meters) for the marine nemertean worm (bootlace worm).
Various kinds of worm occupy a minor variety of parasitic niches, living inside the other animal’s bodies. Free-living worm species don’t live on land but instead live in freshwater or marine environments, or underground by burrowing.
Biologically, ‘worm’ refers to an outdated taxon (vermes) used by Jean-Baptiste Lamarck and Carolus Linnaeus for any non-arthropod invertebrate animal, and comes from the Ancient English word wyrm.
wormMany creatures known as ‘worms’ are invertebrates, but this term is still used for the slow worm Anguis, a legless burrowing lizard, and the amphibian caecilians. Invertebrate animals usually called ‘worms’ include nematodes (roundworms), annelids (earthworms), Platyhelminthes (flatworms), marine nemertean worms (“bootlace worms”), marine polychaete worms (bristle worms), priapulid worms, marine Chaetognatha (arrow worms), and insect larvae like maggots and grubs.
Worms may also be referred to as helminths, specifically in medical terminology when mentioning parasitic worms, especially the Cestoda (tapeworms) and Nematoda (roundworms) that live in the intestines of their host. When a human or an animal is said to ‘have worms,’ it means that it’s infested with parasitic worms, typically tapeworms or roundworms.
Worms live in nearly all continents of the world including freshwater, marine, and terrestrial habitats. Some worms living underground assist to condition the soil (e.g. annelids). Most of them thrive as parasites of animals, including humans (e.g. Platyhelminthes,) and plants (e.g. aschelminths).
Many other worms may be non-parasitic, or free-living. There are worms which live in seawater, freshwater, and even on the seashore. Ecologically, worms form an essential link in the food chains in nearly all the ecosystems on Earth.
In the US, the worms’ average population per acre is about 53,767. Northern forests in the United States were once free of the worm.
There are thousands of species which live in a broad variety of habitats other than soil. With time, this comprehensive definition narrowed to the modern definition, even though this also includes many different animal groups.
To many people, the several familiar worms are the earthworms. They belong to the phylum Annelida. In general, earthworms have existed for almost 120 million years. They aerate and enrich the soil; Charles Darwin discovered that worms turn more than the top 15 cm (6 inches) of topsoil in every 20 years in a field close to where he lived.
In less favorable conditions, like hard soil or waterlogged soils deficient in an appropriate organic matter, or in seasonally dry soils, they can’t attain anything like that. They don’t have a brain in the sense of a vertebrate brain but possess nerve centers (known as ganglia). They also don’t have eyes but can easily detect light with photoreceptors. Worms are known to be hermaphrodites (both sexes in only one animal) but can cross fertilize.
Earthworm belongs to invertebrates group. It has a very soft body, shaped like a tube. There are about 6000 species of earthworms which are native to Europe. They are broadly distributed in the North America and Asia today.
Earthworms inhabit the moist soil. These creatures are so important since they improve soil fertility and represent an essential part of the diet to several animals in the wild. Earthworms are even consumed as a delicacy in some regions of the world.
Species of worms which live on the farmlands are usually victims of the chemical pollution (pesticides).Other species of earthworms are many in the wild. Are you looking for some fun facts about worms? If yes, then read on.
