Common Cusimanse

<em>Crossarchus obscurus</em>, commonly known as the common cusimanse or long-nosed cusimanse, is a small social mongoose in the family Herpestidae. This species is native to the rainforests and dense tropical forests of West and Central Africa. Common cusimanses are highly social animals that typically live in family groups and forage cooperatively on the forest floor, using their elongated, flexible snouts to root through leaf litter and soil in search of invertebrates, small vertebrates, and fallen fruits. They communicate through a variety of vocalizations and are known to mob and harass potential predators. The species is diurnal and terrestrial, sheltering in burrows or dense vegetation at night. Common cusimanses are assessed as Least Concern by the IUCN, with populations considered stable across their range. Biological traits such as lifespan and body measurements remain poorly documented in the scientific literature.

common earthworm

<em>Lumbricus terrestris</em>, the common earthworm, is one of the most ecologically significant invertebrates in temperate soils and is native to Europe, with introduced populations established across North America and other regions globally. The species is not evaluated by the IUCN Red List. <em>Lumbricus terrestris</em> belongs to the family Lumbricidae and is widely distributed across Belgium, Denmark, Germany, Norway, Sweden, the United Kingdom, the United States, and other countries in its introduced range. It typically inhabits moist, organic-rich soils in gardens, agricultural fields, woodlands, and grasslands, burrowing deep into the substrate and surfacing at night or after rainfall to feed on decomposing leaf litter and soil organic matter. As a detritivore and ecosystem engineer, the common earthworm dramatically improves soil structure, aeration, drainage, and fertility through its burrowing activity and the production of nutrient-rich castings. It is a critical food source for a wide range of predators including birds, mammals, amphibians, and invertebrates. Charles Darwin extensively studied <em>Lumbricus terrestris</em> and recognized its profound role in soil formation and ecosystem functioning in his 1881 publication on the subject. Biological traits of this species remain poorly documented in the scientific literature.
