🦭Caspian seal

Pusa caspica (Gmelin, 1788)

La foca del Caspio (Pusa caspica) es una especie de mamífero pinnípedo de la familia de los fócidos.​ Es uno de los miembros más pequeños de esta familia, vive exclusivamente en las aguas salobres del mar Caspio. Se ubica a lo largo de las costas, en muchas islas rocosas y bloques de hielo a la deriva. En invierno y en períodos más frescos de la primavera y el otoño, estos mamíferos marinos migran hacia el norte de este mar. Durante el verano, cuando el hielo se derrite, aglomeran frente en la desembocadura del río Volga y del Ural, y hacia el Sur donde las aguas son más frías, debido a su mayor profundidad. No está claro cómo estas focas se aislaron en el mar Caspio y existen varios supuestos; uno de los más aceptados es que estos animales penetraron por el norte del mar Caspio durante el Pleistoceno con el avance de los glaciales continentales. Sin embargo, también pudo haber sucedido en el Plioceno Tardío, en un período de glaciación, hace alrededor de 2 millones de años. Actualmente se acepta que la foca del Caspio junto con la foca del Baikal (otra especie aislada en la cuenca de Eurasia), son descendientes de la foca anillada.
