Péramèle Épineux

<em>Echymipera kalubu</em>, the common echymipera, is a spiny bandicoot in the order Peramelemorphia, family Peramelidae, classified as Least Concern by the IUCN Red List. Geographic range data for this species are limited; it is associated with diverse terrestrial and aquatic habitats in its distribution area, which encompasses parts of New Guinea and nearby islands in the Australasian region. Like other members of its family, <em>Echymipera kalubu</em> is a small to medium-sized marsupial with a pointed snout, compact body, and coarse, spiny fur that provides protection against predators. Bandicoots are omnivorous foragers, typically using their elongated snouts to probe soil and leaf litter for invertebrates, plant tubers, fungi, and small vertebrates. <em>Echymipera kalubu</em> is nocturnal and typically solitary, with individuals occupying home ranges in forest, scrub, and disturbed habitats. The species reproduces with a relatively short gestation period, characteristic of marsupials, with young completing development attached to teats within the mother's backward-opening pouch. Bandicoots perform important ecosystem functions as soil disturbers and seed dispersers. Biological traits of this species remain poorly documented in the scientific literature.

Petit opossum-souris

The Common Fat-tailed Mouse Opossum (<em>Thylamys pusillus</em>) is a small marsupial belonging to the genus Thylamys within the family Didelphidae. Like other members of its genus, this species typically stores fat in its tail, which becomes swollen during periods of food abundance and is metabolised during leaner times, a physiological adaptation that provides energy reserves. <em>Thylamys pusillus</em> is generally found in diverse terrestrial and aquatic ecosystems, often in dry woodlands, scrublands, and grassland habitats of South America. The species is assessed as Least Concern on the IUCN Red List, indicating it is not currently considered at risk of extinction. Detailed geographic range data are not available in the current record, but members of this genus are typically distributed across parts of Argentina, Bolivia, Paraguay, and Uruguay. Biological traits including average lifespan, body dimensions, and specific dietary composition remain poorly documented in the scientific literature, though Thylamys species are generally considered omnivorous, often consuming insects, small vertebrates, and plant material.
