National Doughnut Day is Friday, June 2, this year. Here at the New England Aquarium the Northern fur seals and California sea lions are celebrating with a box of treats from “Sunkin’ Donuts!” Our Marine Mammals staff made this special box of goodies from the animal’s favorite things: gelatin, ice, and fish! 

Watch as the Northern fur seals and California sea lions gobble down these delicious treats!

The delectable gelatin doughnuts are hand-decorated with silverside (a type of fish) “sprinkles” and squid tentacle “icing.” Forget Boston cream or jelly doughnuts, these ice doughnuts are stuffed with capelin (also a type of fish) and whole squid! Mmmmm…doughnuts.

The gelatin doughnuts are colored with natural plant-based food coloring. Not only is gelatin fun for the animals to play with, but is also incredibly hydrating. Seals and sea lions do not usually drink water, instead they get all of the water they need through the fish they eat. And because there is so much water in gelatin, it’s another way we can provide fresh water for our animals. Plus, how fun!

Here’s a look at this special enrichment activity.

And Happy Doughnut Day!
