Common Hound'S-Tongue

<em>Cynoglossum officinale</em>, commonly known as common hound's tongue, is a biennial herb in the family Boraginaceae. It is classified as Least Concern on the IUCN Red List, with populations documented across Europe — including eight European countries — and North America. The species typically inhabits disturbed soils, roadsides, dry grasslands, coastal dunes, and open woodland edges in temperate climates. It is recognized by its deep reddish-purple flowers and rough, tongue-shaped leaves that give the plant its common name. The species contains pyrrolizidine alkaloids and has been used historically in folk medicine, though it is considered toxic to livestock. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.

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.
