Orca común

El mayor miembro de la familia de los delfínidos, la orca (Orcinus orca) puede alcanzar hasta 9 metros de longitud y 6 toneladas de peso, y se encuentra en todos los océanos desde el Ártico hasta el Antártico. Es un depredador apex que vive en grupos matrilineales con dialectos distintos, estrategias de caza y tradiciones culturales que difieren entre poblaciones. Algunas poblaciones se especializan en peces, otras en mamíferos marinos. Sin depredadores naturales, las orcas ocupan la cima de todas las cadenas tróficas marinas que habitan.
