[Note Guidelines] Photographer's Note
I remember dissecting these slimy little guys back in high school during biology class. I was only a sophomore, but still vividly recall having to memorize each body part and know exactly what it's function was.

I also remember my biology teacher describing how earth worms had both male and female organs. This was very interesting to us guys, yet a little embarrassing to talk about since our class had both boys and girls in it. All I can say is that we've come a long way since those innocent childhood days of my era.

I will post the original image in the Workshop.

Lumbricus Terrestris, or the common earthworm leads a relatively important life. After birth, worms are expected to live up to three years and sometimes up to ten years in captivity. Worms swarm under our feet by the thousands, tunneling and burrowing their way around, this helps loosen up the soil and promote root growth. Earthworms lay eggs mainly in the spring and fall, when the moisture levels of the soil are high. Earthworms are hermaphrodites, meaning they have both female and male reproductive systems. Although they have both sex organs, it still takes two worms to produce offspring. The worms meet at the heads, then the setae in the clitellum of each worm pierce the body of the other worm to lock their bodies together. The slime tube around the clitellum encircles the worms making the worms joint more firmly. Then sperm from each worm is released through the body until it reaches the sperm sac. This process takes about two or three hours. After the worms have finished receiving each otherís sperm, it releases each other and go their separate ways. In a couple of days the cocoons are ready and released into the ground in their burrows where they remain unharmed until they mature. The worms usually take about two or three weeks to develop. The mature worm spends the rest of its life burrowing through the ground eating the dirt and absorbing the needed nutrients and release castings that are very fertile and promote plant growth.

Dear Ron,
Great capture which I had learnt in biology class only to see it today on TN otherwise. TFS
Regards _Subhash

hello Ron

WOW ! for a midnight shot with tripod and flash
this is a great photo, i love much better the one of
the WS because we see more of their environment,

TFS

Asbed

Hi Ron,

An excellent close-up of these amorous critters. Excellent sharpness and color, right down to their slime.

All my life I've read that they're good for the soil, but now we're finding out that most of northern North America lost its native earthworms as a result of the Ice Age, and it seems that all our earthworms are now from other parts of the world and they're apparently doing severe damage to forest ecosystems because they consume the leaf litter needed for a healthy forest.

That's why it's important to not discard worms when we're done fishing, and shouldn't deliberately spread them around any more than they already are.

Thanks,
John

Excellent note too.
