The National Aquarium in Baltimore, Maryland is undertaking groundbreaking changes in the way they care for the dolphin colony raised in captivity at the facility. With a mission to “advance understanding and protection of cetaceans by offering a natural environment in which the colony of dolphins in (their) care will thrive,” the aquarium is establishing the first dolphin sanctuary in North America. The colony of 8 dolphins will be moved by the year 2020 from the 35-year old Inner Harbor attraction at the Marine Mammal Pavilion.
