Mel, the Killer Whale or Orca (Orcinus orca) narrowly misses out on a South American Sea Lion (Otaria flavescens) that it was hunting, in Patagonia. Of the 18 only 7 have mastered the stranding behaviour whereby the Orca enters the shallow surf to feed on Sea Lion pups. Distinctive by his 2 metre dorsal fin, Mel is an expert hunter who feeds on Sea Lion pups before taking them back to his pod. This lucky Sea Lion however managed to escape the hunter's attentions.
