For some, The Maritime Aquarium is a place with too much stimuli. So on Sun., April 7, the Aquarium is planning a special morning to give guests with sensory-processing differences a fun, comfortable and accepting environment.

On "Sensory-Friendly Morning," lights in the Aquarium will be lower, and music and other sounds will be turned down or off.

The Aquarium also will show specially selected IMAX movies, with lower volume and the theater lights less dim. Choose from 'Born to be Wild' at 9 a.m. and 'Oceans: Our Blue Planet' at 10 a.m.

Also on April 7, a special low-volume seal-training demonstration is planned for 8:30 a.m. And the regular 11:45 a.m. seal-training demonstration will be delayed until noon. A “quiet room” will be available for guests who need a place to calm. For families that need to leave within the first 30 minutes of arrival, passes will be available to come back and try again another day.

The discounted admission prices at the door between 8 and 9:30 a.m. on Feb. 3 are: $21 for adults; $20 for seniors (65+); and $16 for children (3-12). Normal admission prices will resume after 9:30 a.m.: $24.95 for adults; $22.95 for seniors; and $17.95 for children. Kids under 3 are free.
