Common Big-eared Bat

The common big-eared bat (<em>Micronycteris microtis</em>) is a small insectivorous bat belonging to the family Phyllostomidae, native to tropical and subtropical regions of South America. Its range includes Colombia and Venezuela, where it typically inhabits diverse terrestrial and aquatic environments including forests and riparian zones. It is classified as Least Concern on the IUCN Red List, indicating a relatively stable population. As its common name suggests, <em>Micronycteris microtis</em> is distinguished by notably large ears relative to its body size, which enhance its echolocation capabilities for detecting prey and navigating complex forest environments. The species is often associated with lowland and foothill forests, roosting in caves, hollow trees, and dense vegetation. It typically feeds on insects and may also consume small vertebrates or fruit on occasion. Biological traits of this species remain poorly documented in the scientific literature.

house mouse

Among the most widespread and numerous mammals on Earth, house mice originated in South Asia and have accompanied human civilization across every continent except Antarctica. Weighing just 15–25 g, they are highly adaptable omnivores capable of surviving on minimal food and water. As the world's most commonly used laboratory animal, the house mouse has contributed to virtually every branch of biomedical research. They cause significant agricultural damage globally.
