Sea Squirts classes introduce your child to the wonders of the aquatic world while focusing on their developing motor and language skills and encouraging the development of early science skills such as observation and exploration.

Similar classes are available for children 12 to 24 months old through our Sea Squirts Preview classes.


Classes run for one hour and include free play, circle time with songs, stories and activities, art projects, live animals when appropriate and a visit to the Aquarium exhibits. Each series consists of four weekly classes. There is a fee of $55.00 for members and $100.00 for non-members for each series of four classes. Adults are included in the cost of each child. Aquarium admission is included in the cost for non-members as classes end in the Aquarium. A $2 service fee will be added to each ticket for non-members. If younger siblings are close enough in age to participate, they may require registration themselves.Classes are held in the Aquarium's Ocean Center, which is across the plaza from the main Aquarium building. Our winter weather cancellation policy is as follows: Sea squirts classes are cancelled when either the Aquarium or Boston Public Schools are closed.


These popular programs fill up quickly. If your preferred class is full, you will be put on a waitlist and alerted if any slots become available for you and your child. A minimum of five child participants will be required to run a session.
