More Photos
Just wanna share... Maybe its just a little... but i really happy to see the progress and increasing of our worms....
The Latest Worm's Photo
Here are some new photos of our worms. Thanks to God that our worms are increasing by time to time.
Just look at it... Whoooww... Geli kan? Huhu...But i still have to touch it...
Lets enjoy some of the photos...
Our baby worms also has grown up... Hehe...
Our baby worms has increased and healthy grown... When first time i separated them, its just toooooo small, and now its been like this(see the pic).
And here are some of our worm's eggs.

How Are Earthworms Constructed?
Here are some visible and invisible adaptations to admire about earthworm physique:
>> The worm's streamlined body with no conspicuous appendages is an adaptation to living in narrow burrows underground In those narrow tunnels, antenna and fancy tails would just get in the way.
>> Earthworms don't have eyes, but they do have light-sensitive cells scattered in their outer skin. These cells don't enable earthworms to see images, or forms, but they do give their skin the capacity to detect light and changes in light intensity. The worm's skin cells are also sensitive to touch and chemicals
>> Earthworms have simple brains which specialize in directing body movement in response to light, and not much else. To show how simple the brain is, if an earthworm's brain is removed, changes in its general behavior are hardly noticeable
>> Earthworms, as the drawing above shows, possess five hearts. The calciferous glands shown between the hearts manage excess calcium in the worm's diet, a problem you may have if you eat a lot of dirt.
>> Earthworms have no lungs. Their "breathing" consists of oxygen from the air passively diffusing through the skin into the body. One problem with having such permeable skin is that earthworms dry out easily, but not as easily as mollusks
>> Each earthworm carries both male and female reproductive parts --they are, like snails and slugs, hermaphroditic

How Do Earthworms Reproduce?
This matter is as complex as it is interesting, so put your mind in low gear and hold on... Here's a drawing to help you keep oriented:
First of all, not every earthworm segment bears sex organs. Counting from the front, the worm's male sex cells lie in segments 10 and 11. From here the sperm pass through sperm ducts to two male genital openings on the bottom of segment 15. On segments 9 and 10 there are two minuscule sacs called sperm receptacles, or pores, where, during earthworm sex, sperm are deposited. However, this is not where eggs are produced. The egg-producing ovaries reside in segment 13, from which eggs are released through the female pores into egg sacs in segment 14. Finally, there's a rubbery, arm-band-like thing covering the worm's body from segments 31 or 32 to 37, and this is called the clitellum.
Now, when two earthworms mate, they line up next to one another with their "heads" pointing in opposite directions. The clitellum of one worm lies opposite segments 9-11 of the other, which, you'll remember, contain the male parts. The worms now secrete tremendous amounts of mucus, until each is enclosed in a slime tube extending from segment 9 to the rear end of the clitellum at segment 37. Now sperm are ejaculated from segment 15 and carried backward in tubes formed by grooves in the body touching the slime tube and the sperm pass to the sperm receptacles on segments 9 and 10 of the other worm.
Then the earthworms go their different ways. Sex is done. However, that is not to say that eggs have been fertilized, because they haven't. It's just that now, in each worm's sperm receptacles, there are sperm from the other worm.
The next step in producing baby earthworms comes when the earthworm is by itself. Its clitellum secretes a second mucous ring that slides forward over the worm's body. When the ring passes the openings in segment 14, several ripe eggs leave the body and stick to the ring. The ring keeps moving forward until it passes the sperm receptacles in segments 9 and 10, and here sperm come into contact with eggs. Finally, within the mucous ring, the eggs are fertilized.
Now the ring containing the fertilized eggs slips off the worm's "head," seals at both ends, and becomes a sort of cocoon, which is left lying in the soil. Ultimately the eggs hatch and tiny worms escape from the mucous ring, into the soil.

Achieve your Ambition with Rearing Worms / Merealisasikan Impian dengan Penternakan Cacing
Warna medium pada gambar diatas agak coklat dan terang, ini bermakna masih terdapat makanan didalam medium tersebut.
Ini adalah cacing2 yang kami beli sebagai permulaan. Kami mendapat bekalan ini daripada penternak dari Tampin (Angah)
Cacing2 induk dan pra-matang.
Medium cacing atau makanan cacing yang terhasil dari campuran taik kambing dan habuk papan.
Ketika proses pengasingan cacing dari medium untuk penghasilan baja. Cacing2 kelihatan berkumpul dan ia harus dileraikan apabila dimasukkan ke dalam medium baru.
