Spend a minute to hang out with Sam, the giant pacific octopus! 🐙

Ever wonder what a prehensile-tailed skink smells, sees, and tastes?

Science in 60: tracking wild seals

Caption this post. Winner gets a virtual boop.

By collecting non-invasive, simple breath samples, the research team and belugas at Mystic Aquarium are helping us unlock new ways to study whale health. The research we refine here will soon be applied to belugas in the wild in Canada this summer! #BelugaResearch #MysticAquarium

Repeat after me, cameras are friends, not food.

Current mood going into the weekend…

Happy 1st Birthday to Denahi or “Denny” the northern fur seal! Denny now weighs about 45 lbs and chows down on 7.5 lbs of fish a day—though squid might just be the favorite on the menu... 🦭🦑🎂 Happy birthday Denny!!

Join Nuna, the spotted seal during one of her training sessions! These training sessions are important for a variety of reasons including enrichment, voluntary behavior health checks, animal/trainer bonding, and more!

Fun fact about Maia, the California sea lion: sometimes she’s a little shy and has the quietest vocals of all the sea lions at the Aquarium. She’s still a perfect lady though!

Why do sea lions vocalize?

Happy 23rd birthday Juno!! 🎂

When they call you a silly goose, but you’re actually a serious California sea lion…

Just like our ocean friends, we know that diversity makes the world a brighter, more beautiful place. This month (and every month), we’re celebrating love, identity, and being your true, authentic self — no matter how you swim through life. 🏳️‍🌈

Happy 19th Birthday to Sitka, the steller sea lion! 🎂🥳

On World Sea Lion Day we celebrate our fine flippered friends! It is our privilege to provide a forever home for our species ambassadors, many of whom received a second-chance at life here at Mystic Aquarium. We also celebrate the animal care professionals who work with them every day!

Have you ever seen a health exam on a cownose ray? During this procedure, the animal is anesthetized, and the husbandry and veterinary teams work together to draw blood, take measurements and weights, ultrasound the animal to look at their organs and do a thorough visual external examination.

May the 4th be with you!

How do beluga whales sleep?

Today is World Veterinary Day, a day we celebrate some of the real life super heroes that work at Mystic Aquarium. This group of committed professionals delivers the highest level of care for our animals every hour of every day, all year round. Thank you for all you do!

The African penguin chicks at Mystic Aquarium have been introduced to water as they start to prepare for their first swim and integrating with the full colony on habitat!

Happy Easter to all those celebrating!

What’s a California sea lions favorite school subject? 🤔

We should all strive for a nap routine like Yura, the Northern fur seal. Did you know Northern fur seals have the second densest coat of any animal with 300,000 hairs per square inch!?

When the camera catches you mid stretch first thing in the morning.

Cownose rays can find food in a fascinating way – through electroreception! They can sense tiny electric signals that shellfish give off, making it easier to find their next meal buried in the sand.

Tongue out, vibes high.

We're excited to share about a new species that now calls the Marsh Trek at Mystic Aquarium home! The rare spotted catfish is genuinely one of a kind. This elusive freshwater creature has never been seen by most, some even argue its existence.

We're excited to share that Denahi, the Northern fur seal pup born last year at the Aquarium has joined the other fur seals in our Pacific Northwest Habitat! Denahi and the other Northern fur seals at Mystic Aquarium comprise the largest colony of fur seals in the United States.
