      Study: Dolphins See Own Reflections

      By PAUL RECER, AP Science Writer

      WASHINGTON (AP) - Bottlenose dolphins can recognize themselves in a mirror,
      an
      advanced intellectual ability observed previously only in humans and apes, a
      study finds.

      Researchers at the New York Aquarium installed mirrors so that they could be
      seen by two bottlenosed dolphins and then tested to see if the animals were
      self-aware enough to look at the reflected image of markings on their
      bodies.

      Diana Reiss of Columbia University and Lori Marino of Emory University
      report
      on Tuesday in the Proceedings of the National Academy of Sciences that both
      animals responded by looking long and hard at temporary ink marks placed on
      their face and sides.

      Mirror Tests Reflect Dolphins' Intelligence

      By Will Dunham

      WASHINGTON (Reuters) - In a reflection of their intelligence, bottlenose
      dolphins named Presley and Tab at the New York Aquarium have displayed the
      ability to recognize themselves in a mirror -- a quality previously seen
      only
      in people and the great apes, researchers said on Monday.

      The two male dolphins were housed in a pool with reflective glass walls at
      the
      aquarium in Brooklyn. Researchers found the dolphins reacted to their own
      reflections without the social responses they displayed when seeing other
      dolphins.

      Brainy Dolphins Pass the Human 'Mirror' Test
      By MARK DERR

      With brains second only to those of humans in relative size, superb
      memories,
      sonar systems more sophisticated than any navy's, and complex social
      structures, dolphins are often considered geniuses of the seas.

      Clever mimics and quick learners, dolphins have an uncanny ability to
      confound
      researchers, those who have studied them in captivity and in the wild say.
      But
      in recent decades, scientists have made progress in unraveling the
      complexities
      of the dolphin's mind and social life, and have begun to create a detailed
      portrait of these remarkable animals.
