The Baltimore Sun today reports that "The National Aquarium officials are considering no longer having dolphins on exhibit, putting the popular Inner Harbor attraction at the forefront of a debate over whether keeping the animals in captivity is cruel.

The aquarium is considering moving the eight mammals from the Dolphin Discovery amphitheater to an ocean-side sanctuary at an undetermined location. It has hired a team of consultants to examine the issue as part of a broader strategic assessment to ensure a "healthy future for the nonprofit institution and its animals."
