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.

Delfín tonina

La especie de delfín más estudiada y reconocida, los delfines mulares habitan océanos cálidos y templados de todo el mundo, desde las aguas costeras poco profundas hasta el mar abierto. Altamente inteligentes con grandes cerebros en relación con el tamaño corporal, demuestran autoreconocimiento, comunicación compleja y aprendizaje social. Viven en sociedades fluidas de fisión-fusión y cooperan para arrear peces. Una especie indicadora clave de la salud del ecosistema marino.
