Ardilla Gris Oriental

La ardilla gris oriental (Sciurus carolinensis) es nativa del este de Norteamérica y ha sido introducida en numerosas regiones del mundo por su alta adaptabilidad a entornos urbanos. Su estado de conservación es de preocupación menor (LC), aunque en países como el Reino Unido e Italia se considera una especie invasora que amenaza a la ardilla roja autóctona.

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.
