<em>Comatricha pulchella</em> is a myxomycete in the class Myxomycetes, order Stemonitidales, belonging to the genus <em>Comatricha</em>. The species name, meaning beautiful in Latin, may allude to the delicate aesthetic of its sporangia, which are characteristic of the genus in having a stalked structure with an internal filamentous capillitium. <em>C. pulchella</em> occurs on rotting wood and plant litter in moist, forested environments. Like other species in the genus, it progresses through a motile plasmodial feeding stage before developing into sporangia that release spores adapted for wind dispersal. The species contributes to decomposition within forest ecosystems by consuming bacteria and other microorganisms during the plasmodial phase. No geographic range data are specified in the current record. Quantitative biological metrics are not applicable to this organism, and it has not been evaluated by the IUCN.

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.
