Emperor Penguins -v- Leopard Seals in Antarctica

tags: , , , , , , , ,

Emperor Penguins, Aptenodytes forsteri, return from the seas to feed their young. Dramatic scenes unfold as they hesitate at the edge of the Antarctic sea ice after spotting a Leopard Seal, Hydrurga leptonyx, on the prowl under the Antarctic ice. Narrated by the incomparable David Attenborough.

Like many 'generalised' carnivores, the Common or Harbour seal Phoca vitulina is a surprisingly adaptable predator, even if it is rather conservative in diet and choice of foraging habitat (e.g., Tollit et al. 1998).

I always think of the chicks left behind by the death of the few penguins who are eaten by leopard seals. What happens to them? Is their sole parent able to care for them? Does the sole parent find another mate who will reject the chick?

Something I need you to blog about from Antarctica.
