Cachona

El gran tiburón martillo (Sphyrna mokarran), la mayor especie de tiburón martillo, alcanza hasta 6 metros y se encuentra en aguas costeras tropicales y subtropicales de todo el mundo. Su distintiva cabeza en forma de T (cefalofolia) aumenta dramáticamente la superficie sensorial para la electrorrecepción, permitiéndole detectar rayas enterradas bajo la arena con excepcional precisión — las rayas son su presa preferida. En Peligro Crítico, con poblaciones que han disminuido drásticamente debido a las aletas de alto valor y la mortalidad como captura incidental.

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.
