🐋Gray whale
La ballena gris (Eschrichtius robustus) es una especie de cetáceo misticeto de la familia Eschrichtiidae de tamaño medio que en la actualidad sólo habita la zona norte del océano Pacífico y zona norte del Océano Atlántico. Pese a su nombre de “ballena”, los estudios moleculares y morfológicos demuestran que se encuentran más relacionadas con los rorcuales que con las ballenas. Es uno de los mamíferos que realizan una de las migraciones más largas, pues se desplaza desde las bahías del norte de México, donde la hembra pare a su cría en invierno, hasta el norte del mar de Bering, donde se alimenta en verano. Esta presente también en el océano Atlántico norte y en las aguas situadas entre Japón y la península rusa de Kamchatka, pero estuvo cerca de desaparecer en el océano Pacífico occidental, y en el Atlántico Norte.
