Segmented Worms: Marine worms, earthworms, leeches, etc. Annelids

Description

MATING Their heads will face in opposite directions and they will put their clitellums together. Sperm will pass from one worm to another and it will be stored in sacs. After this step is done, a cocoon will form on each of the worm’s clitellum’s. The cocoons will each hold about one to five baby worms and the conditions are very important in order for the cocoons to hatch. It has to be dry and the cocoons can keep for years until the conditions are just right before hatching.

Not so much from the machine, as they flee from vibration, but mostly because their food supply is depleted rapidly when exposed to oxygen. If you rototill, you should immediately cover the area with partially finished compost or waterlogged leaves. The most common garden earthworm, the nightcrawler (lumbricus terristris) is not native to North America and was in fact brought,over in potted plants by Europeans. Most of the native North American earthworms were killed during the last Ice Age 10 to 15 thousand years ago. This is one case of where the accidental introduction of a foreign species has been beneficial..
Slime, a secretion of earthworms, contains nitrogen. Nitrogen is an important nutrient for plants. The sticky slime helps to hold clusters of soil particles together in formations called aggregates. In one acre of land, there can be more than a million earthworms. Baby worms are not born. They hatch from cocoons smaller than a grain of rice. Worms can eat their weight each day..
In addition to removing excess blood that pools up harmfully in reattached digits, leeches exude analgesic, anticoagulant and vasodilation chemicals that make them uniquely effective in reattachments..
