Hi Carson,

MelissaB gave you a really informative web site. However, since you posted again, here are some more sites for you to explore:

Hello,

Although MelissaB and mostman have provided some great sites, remember that the experts here are not here just to provide answers to questions that can be easily searched for on an Internet search engine. Just Google for a few keywords, like "earthworms", "redworms", and "castings". I'm sure that you can find a lot of information that would be beneficial to your project.

Also, when you are comparing between "earthworms" and "redworms", i'm guessing by earthworm you mean nightcrawlers (earthworms you find on the street on rainy days), since redworms are also a type of earthworm. Here is some information about redworms: http://en.wikipedia.org/wiki/Eisenia_fetida. A comparison between redworms and nightcrawlers is also explained in more detail here: http://www.gartersnake.info/articles/00 ... rms_.phtml.

Hope this helps!

I got this from wikipedia....


Earthworm is the common name for the largest members of Oligochaeta (which is either a class or subclass depending on the author) in the phylum Annelida. The earthworm is the most known worm in America, and other countries. In classical systems they were placed in the order Opisthopora, on the basis of the male pores opening posterior to the female pores, even though the internal male segments are anterior to the female. Theoretical cladistic studies have placed them instead in the suborder Lumbricina of the order Haplotaxida, but this may again soon change. Folk names for the earthworm include "dew-worm", "rainworm", "night crawler" and "angleworm" (due to its use as fishing bait).

Earthworms are also called megadriles (or big worms), as opposed to the microdriles (or small worms) in the families Tubificidae, Lumbriculidae, and Enchytraeidae, among others. The megadriles are characterized by having a multilayered clitellum (which is much more obvious than the single-layered one of the microdriles), a vascular system with true capillaries, and male pores behind the female pores.
