Dictyota dichotoma es un alga parda común con frondes planas, repetidamente bifurcadas y de color verde oliva a marrón dorado, que forma talos en forma de abanico. Habita orillas rocosas intermareales y submareales someras de mares templados a tropicales de todo el mundo.

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.
