He believed that earthworms are wholly responsible for the top layer of rich soil on the Earth. Optimum production of African Nightcrawlers is between 70 F and 85F. It is known for its ability to quickly produce worm castings, which are beneficial in the speedy decomposition of compost, and it has recently gained popularity in the North American market as the popularity of home composting has gained momentum and become more widespread. The way some worms tunnel also helps to move fertilizer applications below soil where they can be utilized by the plants more effectively. When he was doing this, he ignored the other label inserted in the bottle, which [was most likely] the original made at the time when Rapp's material was deposited in the NHM[33]. Further comparison of specimens at the British Museum of Natural History (BMNH) by Plisko showed that although Beddard's (l886a,b) comprehensive description of rappi clearly distinguishes it from microchaetus, other data supplied later by Beddard (1895) include characters for both rappi and microchaetus.[34]. The last known sighting of this worm was in 2008. Answer: Few miles. They have a streamlined shape that allows them to burrow through soil. The pink morphs have a slightly yellow colored ring near their top end, and if you look closely at the underside of the saddle, you may be able to see three discs that look like suckers.

For example, a worm that is good for composting will likely be an epigeic worm, as these worms feed voraciously and quickly excrete nutrients to help with the decomposition of compost. Benham described the mouth as nearly terminal, overlapped by the small prostomium large and circular, and its anus as subterminal, [with a] horizontal slit[17]. Of all of the earthworms known in North America, over 30 percent of them are introduced. This physical alteration means that water and soluble nutrients can travel more easily down to the plant roots. Worms are not glamorous creatures that are especially loved by humans, but they play a vital role in our ecosystem, which, as humans, we directly benefit from. The worm also has a low reproduction rate and slow growth, which is further hindering its ability to grow its population. They are also quite efficient at burying and processing small things like coins and random bits of garbage, which they will literally grab and pull below the surface where they can safely process it. The many interesting species (including one with bioluminescence) of native earthworms are affected by some of the more aggressive species which are primarily the successful colonizing invasive species. Temperatures less than 60 F or greater than 86 F for extend periods of time can be fatal. They can drastically range in size, anywhere from one inch to a huge sixty inches in length (University of Alberta). I.
