clublike door snail

Clausilia pumila, the clublike door snail, is a land snail in the family Clausiliidae, a group readily recognized by their sinistral (left-handed) coiling and elongated, spindle-shaped shells. C. pumila has a smooth, glossy shell approximately 12–18 mm in height, tapering to a slender apex, with fine growth lines and a distinctive clausilium—a small, spring-loaded plate inside the aperture that closes when the snail retreats. This clausilium gives the family its common name of door snails. The species is distributed across central and eastern Europe, from Germany and the Czech Republic eastward through Poland and neighboring countries, inhabiting moist deciduous forests, especially beech and mixed woodland with rich ground flora. It is typically found on limestone or calcareous substrates, living under bark, in leaf litter, on mossy rocks and rotting logs, and occasionally on living tree bark. Like other clausiliids, it is a microphytophage, rasping algae, fungi, and decaying plant material from surfaces. C. pumila is classified as Least Concern, being locally common across its range where suitable humid forest habitats persist.

koala

Icónico marsupial del este y sureste de Australia, los koalas pesan hasta 15 kg y pasan hasta 22 horas diarias durmiendo para conservar energía de su dieta de hojas de eucalipto, baja en calorías. Altamente especializados para procesar los compuestos tóxicos del eucalipto que matarían a la mayoría de los demás mamíferos, poseen microbiomas intestinales únicamente adaptados para la desintoxicación. Clasificado como En Peligro en 2022, con poblaciones diezmadas por la enfermedad de clamidia, la deforestación y el cambio climático.
