Owners were allowed to turn in their illegal pets without facing prosecution.
The animals were handed over to zoo and DEP officials.
Owners were asked about the animals' diets, medical history and temperament, but were not required to give their names.
It is illegal to own large and potentially dangerous animals in Connecticut.
The issue came to the forefront after a 200-pound pet chimpanzee viciously attacked a Stamford woman in February.
135 animals in all were turned over to authorities. They included 15 boa constrictors, 15 pythons, seven alligators, a small monkey and an assortment of turtles and parrots.
