Earthworms are environmental indicators of soil health. Earthworms feed on the decaying matter in the soil and analyzing the contents of their digestive tracts gives insight into the overall condition of the soil. The earthworm gut accumulates chemicals, including heavy metals such as cadmium, mercury, zinc, and copper. The population size of ...
The lowland streaked tenrec is active both during the day and at night. Its diet is made up primarily of earthworms, but it will sometimes prey on other invertebrates as well. It may be seen stamping its feet on the ground with its fore-paws, an adaptation which is believed to increase earthworm activity for easier foraging. [8]
This form of activity is often considered a way to escape floods and waterlogged burrows. However, this cannot be the case since L. terrestris, like other earthworms, can live in oxygenated water for long periods of time, stretching to weeks. Under less severe environmental conditions where air temperature and moisture are sufficient, the worm ...
Daniel Pinkwater's 1981 novel The Worms of Kukumlima features giant intelligent earthworms who live in an extinct volcano and collect "elephant mice". The Septimus Heap novel Flyte introduces creatures known as Landwyrms, worm-like creatures with deadly tails that secrete acid.
Earthworms: These slimy things are not just good for fishing bait. They also help keep the plants in your gardens alive by creating holes in the soil for oxygen and nutrients to travel through.
Oligochaetes are well-segmented worms and most have a spacious body cavity (coelom) used as a hydroskeleton.They range in length from less than 0.5 mm (0.02 in) up to 2 to 3 metres (6.6 to 9.8 ft) in the 'giant' species such as the giant Gippsland earthworm (Megascolides australis) and the Mekong worm (Amynthas mekongianus).
Earthworms, as we know, are garden champions, cleaning the soil by eating their weight in organic matter every day and aerating it as they wriggle around, creating tunnels to ease root growth.
Unlike garden-variety earthworms, these flipping, thrashing, invasive miscreants are ravenous consumers of humus, the rich, organic, essential top layer of soil formed by dead and decaying small ...
