esponja cornuda

<em>Axinella polypoides</em>, commonly known as the Common Antlers Sponge, is a marine sponge in the family Axinellidae. This species has not been formally evaluated by the IUCN and has been recorded in waters off Norway, among other European marine environments. The Common Antlers Sponge is an erect, branching sponge that typically forms irregularly branched, tree- or antler-like colonies in yellow to orange coloration, which are visually distinctive on the rocky substrates of the Mediterranean Sea and the northeastern Atlantic Ocean. It typically grows attached to hard substrates such as rocks and corals in subtidal zones, often in areas with moderate to strong water currents that deliver particulate food. As a filter feeder, it draws water through its porous body to extract organic particles and microorganisms. This sponge can reach substantial sizes and is often found in deeper, clear-water habitats. 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.
