South Carolina Aquarium welcomes 2 new otters The addition of the new otters, who just recently turned 1 year old, will ensure that neither Ace nor Stono will be without social support when one passes.

The South Carolina Aquarium says these young otters came to the Aquarium through a Species Survival Plan program coordinated by the Association of Zoos and Aquariums. In 2019, after much thought and consideration, the aquarium’s animal care team says they decided to explore the possibility of adding two new family members to their senior otter duo, Ace and Stono.
