Please note:

Sea Squirts programs conclude in 2019 and will no longer be offered. In 2020, we will be rolling out new programming that enables members of our community to experience the Aquarium in new ways and to join us in our work to protect the blue planet. Click here to learn more about these programs.


Specially designed for children ages 12 to 24 months, the Sea Squirts Preview program is a great introduction to our Sea Squirts classes.

Over the course of four weeks, your child will become more comfortable in our classroom setting and you will become more confident exploring the Aquarium with your children outside of class time. Series are repeated throughout the year, as repetition is one way to support your growing toddler’s development. A minimum of five (5) children participants will be required to run a session.
