Teach Your Children About Earthworm Components.

An earthworm is a member of the Lumbricidae family of terrestrial annelid invertebrates. The name "earthworm" comes from where it resides (earth). Any biome with damp soil or dead plant matter can support them. They are especially prevalent near rivers and rain-forests. They create a necessary contribution to soil fertility and are thus important in gardens and on farm land. Here are some facts about earthworms.

1 - Earthworms are older than the dinosaurs.


Scientists have discovered fossilized worm tunnels that date to the Cambrian period, 270 million years before the emergence of dinosaurs, according to research that was just published in the journal Geology.

2 - Earthworms can become paralysed and die if exposed to sunlight for too long.


Like humans, they have a variety of biomolecules in their skin, including sterol and tetraene. The degeneration of circular and longitudinal muscles and subsequent skin drying caused by sunlight in earthworms If the skin became too dry, earthworms would not be able to breathe and would perish. Vermicomposting is a suitable method for composting indoors because earthworms thrive in mild environments.

3 - Earthworms are both male and female.


Earthworms are simultaneous hermaphrodites because they have both male and female bodily organs. When it has rained and the ground is sufficiently wet, they usually mate. They will need the help of another worm because they are unable to reproduce on their own.

4 - There are many different species on the planet.


According to the United States Natural Resources Conservation Service Department of Agriculture, there are roughly 7,000 different species of earthworms on the planet, which are separated into 23 families. There are more than 100 different worm species in the United States.

5 - Earthworms are animals.


Even though you might not think of worms as animals at first, they actually belong to the animal kingdom. Since they are invertebrates, they have no backbone. They also have cold blood, which prevents them from producing heat on their own like warm-blooded creatures can. This is why it's more likely that you'll see them out and about when the weather is warmer as well. They hibernate underground during the colder months, sometimes even six feet below the surface.

6 - The Giant Gippsland Earthworm is the world's longest.


Only one little area of land near the bottom of the Australian mainland has the Gippsland giant earthworm, a protected species. When the Gippsland giant earthworm was originally found in the 1870s, many thought it was a snake. They can grow to a maximum length of 9.8 ft (3 m), have an average length of 3.3 ft (1 m), and a diameter of 0.79 inches (2 cm).

7 - Earthworms lack eyes, but they're able to see light.


There are no eyes on earthworms. They instead rely on the receptor cells in their skin the receptor cells in their skin. Light and touch are very sensitive to these sensor cells. They have a hydrostatic skeleton and a well-streamlined, svelte physique. They can fit into incredibly small locations thanks to this modification.

8 - Earthworm larvae emerge from cocoons.


About 2–3 cocoons can be produced per week by a mature Red Wiggler worm. Small, lemon-shaped, and golden-yellow in hue, cocoons are round. For Red Wiggler worms, the maturation period between egg development and hatching can be up to 11 weeks. Normally, 2 to 4 baby worms emerge from each cocoon. Until the circumstances are ideal, cocoons might lay dormant for years.

9 - Earthworms are cold-blooded.


Worms are cold-blooded, so they are unable to control their body temperature the way mammals can. This implies that their body temperature will match that of their environment.

10 - An earthworm has a life expectancy of four to eight years.


The life expectancy of worms will vary widely, depending on the species. In a very protected and stable setting, some species of worms will live up to 4–8 years; in the wild, worms have several predators. In general, the typical life of a composting worm is about two years.
