| Summary |
Sharks or Dolphins, two predators, two morphological responses to the same environmental constraints. Which one is the better adapted to survive? An underwater camera passes swiftly over a coralline sandbank then stops on a black and image of a razor fish lurking in wait. But how is it possible to hunt in the darkness of the abyss without this super-sense? Seals have found an answer to this question, thanks to their vibrissae. These whiskers can detect the movements of prey in total darkness. But what can really be seen with these whiskers and how do they use them? That is what a young sea lioness in Patagonia and a grey seal in Scotland learn-- before they suddenly end up in the jaws of a super-predator, a killer whale. How can they resist? To rule over the oceans, this animal an array of senses, a hunting culture transmitted from one generation to the next and an adaptability to changing environmental conditions |
