It looks like pure play: a harbor seal gleefully chasing a rubber duck. But for Reggae at the New England Aquarium in Boston, the toy is part of a training routine meant to keep him learning.
When the 33-year-old Atlantic harbor seal plays fetch with the rubber duck in his habitat built to mimic the region’s rocky shore, he’s practicing memory, problem-solving and focus — skills trainers say are essential to keeping animals in human care mentally and physically engaged.
The routine recently drew attention on social media after the aquarium posted video of Reggae tightly hugging the duck while floating on his belly. In another moment, he sits on a rock with the duck tucked under his flipper, appearing to pat its head.
Watch the video below:
Rebekah Miller, the aquarium’s manager of the pinniped area overseeing the Atlantic harbor seals and California sea lions, said enrichment is central to the seals’ daily lives.
“He can use his great vision to look around the habitat, find these new items, and he can also use his other senses to kind of explore,” she said. “It’s a great way to challenge our animals. We want to create challenges for them and really allow them to use those problem-solving skills that they have.”
The sessions are designed not just to stimulate the seals cognitively but to strengthen relationships with trainers, with even physical play — manipulating objects with their front flippers or moving a toy through the water — becoming part of that challenge.
On a recent morning, trainer Liz Wait stood at the edge of the exhibit with a silver bucket of fish clipped to her waist, tossing small rewards as Reggae followed cues.
“Target!” she called, pointing to one duck. Reggae swam over and nudged it with his nose. She repeated the cue with another duck.
“Hold it!” she said, placing a rubber duck on his white belly. Reggae lifted his flippers to wrap them around it.
“Are you having fun with your ducks?” she asked as he climbed onto a rock, resting his chin atop one of the toys.
“You want to say, ‘Bye, everybody?’” Wait asked, waving her hand. Reggae hoisted his right flipper in response and returned a salute from his trainer. “Good, Bubba.
