Orca or Killer Whale, Erebus & Terror Gulf, Antarctica

The Orca or Killer Whale is the top predator of the Antarctic. It is always seen in small pods patrolling the surrounding waters of the Antarctic Peninsula, in search of its favorite prey, consisting mainly of seals, small whales and penguins. The Antarctic form of this cosmopolitan species differs from other world populations, as they lack the clear white patches; instead these pale areas are stained by a brownish coloration, probably due to the presence of diatoms.

La Orca es el principal predador de la Antártica. Siempre observada en pequeñas manadas que patrullan las aguas aledañas a la Península en busca de sus presas favoritas, especialmente focas, pequeñas ballenas y pingüinos. De distribución cosmopolita, la Orca de aguas antárticas difiere de las otras poblaciones, pues carece de parches completamente blancos; las áreas pálidas están teñidas de una coloración pardusca, que probablemente se debe a la presencia de diatomeas.
