I haven't been there since I was young, many decades ago! Haha. They now have many engaging features for both kids & adults. My nephews loved it, and we all enjoyed the interesting animals & exhibits.
We sat in on a presentation about sea creatures such as shellfish & echinoderms (sea cucumbers, urchins, sea stars, etc). The speaker had a bunch of the live animals in bins w/ water, for the kids to look at afterward.
My favorite animal was definitely the octopus they had in the aquarium room. I could have sat watching it all day as it swam around, changing form & color.
I edited the pics & video of the 'Awesome Octopus' and uploaded it to YouTube:
The enthusiastic & helpful staff also helped me solve a mystery beach find!
