Earthworms are classified into three main ecophysiological categories: (1) leaf litter- or compost-dwelling worms that are nonburrowing, live at the soil-litter interface and eat decomposing organic matter e.g. Eisenia fetida; (2) topsoil- or subsoil-dwelling worms that feed (on soil), burrow and cast within the soil, creating horizontal ...
The majority of aquatic oligochaetes are small, slender worms, whose organs can be seen through the transparent body wall. They burrow into the sediment or live among the vegetation mostly in shallow, freshwater environments. Some are transitional between terrestrial and aquatic habitats, inhabiting swamps, mud or the borders of water bodies.
There are over 22,000 living annelid species, [6] [7] ranging in size from microscopic to the Australian giant Gippsland earthworm and Amynthas mekongianus, which can both grow up to 3 meters (9.8 ft) long [7] [8] [9] to the largest annelid, Microchaetus rappi which can grow up to 6.7 m (22 ft).
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 ...
These worms live in deep burrow systems and require water in their environment to respire. [2] They have relatively long life spans for invertebrates and can take 5 years to reach maturity. The reproductive period of the Giant Gippsland Earthworm mainly spans from September to December. [5]
How nutritious are edible worms and insects? Many are a complete source of protein and high in iron, zinc, magnesium, phosphorus, B-vitamins, amino acids, omega-3 and omega-6 fatty acids and fiber.
The abundance of earthworms is highly correlated to soil pH, texture, water content, and temperature. [26] Earthworms have the ability to biomonitor soil pollutants . [ 27 ] This is because of earthworms' burrowing habit serves to facilitate water flow and agrochemicals through the soil profile, so are able to perform carbon sequestration and ...
Familiar worms include the earthworms, members of phylum Annelida. Other invertebrate groups may be called worms, especially colloquially. In particular, many unrelated insect larvae are called "worms", such as the railroad worm, woodworm, glowworm, bloodworm, butterworm, inchworm, mealworm, silkworm, and woolly bear worm.
