Chyzer's Shining Claw

Chyzer's shining claw (Lamprochernes chyzeri) is a small pseudoscorpion in the family Chernetidae, found in parts of northern and central Europe including Denmark, Norway, and Sweden. Pseudoscorpions are arachnids that superficially resemble scorpions but lack a tail and stinging apparatus; instead they use venom glands in their chelicerae to subdue small invertebrate prey. Lamprochernes chyzeri inhabits decaying wood, bark crevices, leaf litter, and the nests of birds and mammals, where it preys on mites, springtails, and other small arthropods. Like many pseudoscorpions, it practices phoresy—attaching to larger insects such as beetles or flies for passive transport to new habitats. The species has a characteristic shiny or metallic appearance to its carapace, which gives the genus its name. It is classified as Least Concern, with stable populations across its Scandinavian and northern European range. The taxonomy of the genus Lamprochernes has been subject to revision, and some authors recognize closely related species as synonyms. Pseudoscorpions as a group are understudied relative to other arachnid orders, and accurate distribution data for many species, including Lamprochernes chyzeri, remain incomplete. They are generally considered beneficial in ecosystems due to their predatory role in controlling populations of soil and bark-dwelling invertebrates.

Oso Polar

El mayor carnivoro terrestre de la Tierra, el oso polar puede superar los 700 kg y se encuentra en el hielo marino del Artico, desde Canada hasta Rusia. Es un mamifero marino altamente especializado que depende del hielo marino para cazar focas anilladas y barbadas. Excelente nadador capaz de cubrir grandes distancias en agua abierta. Clasificado como Vulnerable, sus poblaciones soportan una presion severa por la rapida perdida de hielo marino artico debida al cambio climatico.
