Big-eared opossum

The Big-eared opossum (Didelphis aurita) is a species in the genus Didelphis. It is currently classified as Least Concern on the IUCN Red List. Typically found in diverse terrestrial and aquatic ecosystems.

Collared Mongoose

The Collared Mongoose, known scientifically as <em>Herpestes semitorquatus</em>, is a small carnivorous mammal belonging to the family Herpestidae. <em>Herpestes semitorquatus</em> is characterised by a distinctive pale collar or band of lighter fur around the neck region, which gives the species its common name and differentiates it from other mongoose species within the genus. Mongooses of the genus Herpestes are typically agile, terrestrial predators that inhabit a range of forested and scrubland environments. They are generally known to feed on invertebrates, small vertebrates, and eggs. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Mongoose is currently assessed as Near Threatened on the IUCN Red List, indicating that while the species does not yet qualify as threatened, it is considered to be close to qualifying, and monitoring of population trends is warranted.
