As trick-or-treating is being canceled around the region in the aftermath of Hurricane Sandy, Sea Research Foundation’s Mystic Aquarium is opening its doors on Wednesday, Oct. 31 from 5 p.m. to 7:30 p.m. for a free, safe, family-friendly trick-or-treating event among the aquarium’s exhibits.

All are welcome to attend and Mystic Aquarium will accommodate as many families as possible during that time. Last admission is at 7:30 p.m. and, once inside, guests may stay until 8 p.m.

Mystic Aquarium did not sustain any damage from the storm and resumes regular business hours on Oct. 31.
