Anything that lives in caves: foxes.

In areas where the sewer system is shared with the storm drains, things that live in and around streams: fish, frogs.

I’ve seen raccoons living in storm sewers. It startled me a bit, biking past, to see a family of masked faces looking up at me from the drain.

There was a Rhinoceros that fell in after the animals in the Central Park Zoo escaped.
.

THE RHINOCEROS escaped, as we have said, toward the Mall. Here he attacked a party of young girls, killing the sewing girl, Annie Thomas, and frightening the others terribly. One of them, subject to heart disease, Ellen Schubert, has received such a nervous shock that her death may be looked for at any moment.

The beast left the Park at one of the upper Eighth avenue entrances, and gored a horse at Ninetieth street, overthrowing the heavy wagon to which he was harnessed, and dislocating the shoulder of Isaac Parker, milkman, who was driving. In this neighborhood he overthrew a shanty on the rocks, which fell before him like a house of cards. The wretched inmates were at supper, and the falling planks took fire. All the family escaped except a child in the cradle, which was burned to a crisp. Continuing on his career until he reached Eleventh avenue, he was followed by a crowd of men and boys, who were evidently unaware of his ferocious nature. He must, too, have been nearly spent with his terrible efforts, but continued on toward the North River.

A fortunate accident put an end to his career. It was now very dark, and he was seen to fall into a sewer excavation on the Boulevard, fifteen feet deep. Had it been a week day, and at an earlier hour, he would, no doubt, have ended his life in killing, by falling on some of the men at work. As it was, he fell ingloriously.
