An earthworm is a soil-dwelling terrestrial invertebrate that belongs to the phylum Annelida. The term is the common name for the largest members of the class (or subclass , depending on the author) Oligochaeta .
Most schools provide students with cadavers for investigation by dissection, aided by dissection manuals, as well as cadaveric atlases (e.g. Netter's, Rohen's). Working intimately with a cadaver during a gross anatomy course has been shown to capture the essence of the patient-provider relationship. [3]
This SVG diagram contains embedded raster graphics. Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size). If appropriate to do so, they should be replaced with images created using vector graphics .
Gippsland earthworm colonies are small and isolated, [9] and the species' low reproductive rates and slow maturation make those small populations vulnerable. [9] Their natural habitats are grasslands, and while they can survive beneath pastures, [9] cultivation, heavy cattle grazing and effluent run-off are adversarial to the species. [9]
