Moniligastridans

Moniligastridans is a taxonomic order of annelid worms belonging to the class Clitellata. These invertebrates are commonly known as earthworms. The most defining characteristic of moniligastridans is their reproductive system, which features testes that are typically arranged in two pairs of segments, with ovaries situated in a more posterior segment. This arrangement distinguishes them from other major earthworm groups like the Lumbricina.

Moniligastridans are found in various terrestrial habitats across the globe, though their distribution can be patchy and is often linked to specific soil conditions. They play a vital role in their ecosystems by contributing to soil aeration, nutrient cycling, and decomposition of organic matter through their burrowing and feeding activities. Their diet consists primarily of organic material found in the soil.

While the exact number of species within Moniligastridans can vary with ongoing research and classification changes, it represents a significant group within the earthworm diversity. Their ecological importance makes them subjects of interest for soil science, ecology, and even agricultural studies.
