Aquarium

BALTIMORE -- Shhhhh.

With two baby dolphins in the house, not only is Baltimore's National Aquarium asking visitors to keep it down, but the infants have also forced the attraction to reconfigure one of its most popular shows just as tourist season launches.

With little ones to consider -- to say nothing of their sensitive mothers -- the usually boisterous dolphin show, known for splashing and shrieking, has turned into a quiet zone, with hushed music, fewer visitors allowed in at a time and a video documenting dolphin births substituting for most of the noisy acrobatics.
