common horse fly

<em>Haematopota pluvialis</em>, commonly known as the common horse fly, is a blood-feeding dipteran insect in the family Tabanidae. It is classified as Least Concern on the IUCN Red List. The species is recorded from Belgium, Denmark, Norway, and Sweden, with a distribution centered in northwestern Europe, where it typically inhabits moist, vegetated areas near water bodies, woodland margins, and pastures. Female horse flies are well known as ectoparasites of large mammals, while males are primarily nectar feeders. Diet information beyond this general feeding ecology is not available in current species 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.
