The Seattle Aquarium yearly exposes select residents to pumpkin, but spokesperson Laura Austin says none of them have developed a taste for the autumnal treat.
"They just play with them," Austin says of the carved pumpkins delivered in conjunction with Halloween. "The river otters, for some reason, they'll actually put the pumpkins on their heads and swim around."
Volunteer divers who compete in the underwater pumpkin carving contest - "divers just love doing things underwater," Austin says of the longstanding tradition which a few years ago became a fixed entry on the aquarium's holiday calendar - leave their completed creations in the display tank.
"The fish might nibble, but it's not their preferred feed," Austin says.
Still, Halloween is considered an eating holiday at the aquarium.
"We do freeze squid parts in cake pans," Austin says of the treats prepared for marine mammals.
