Woodbridge Animal Control Officer Karen Lombardi picked up an injured snapping turtle along Amity Road, north of the intersection with Center Road last week.
The turtle presumably was hit by a car and its shell was crushed.
She said she took it to the Ansonia Nature Center, where she was referred to veterinarian Dr. Jim Micinilio at Countryside Veterinary in Shelton.
He had been successful in saving another turtle a year ago, she said.
However the injuries were too extensive and the turtle had to be euthanized.
Dr. Micinilio found that the turtle was carrying eggs and he managed to extract 53 of them. They are now being incubated until they hatch.
They will be released into the same general area their mother lived, Lombardi said.
