Among the victims of Hurricane Sandy are the New York Aquarium on Coney Island and Jenkinson's Aquarium in Point Pleasant Beach, N.J., which were so badly flooded that they will be closed indefinitely.

The New York Aquarium's residents -- including the famed orphaned baby walrus Mitik, who arrived at the facility from Alaska less than two weeks ago -- may need to be moved to temporary locations, said Jim Breheny, executive vice president of zoos and aquarium for the Wildlife Conservation Society, in a statement late Wednesday.

The entire 14-acre facility was left underwater by a surge of floodwaters. The staff members who rode out the storm at the aquarium have established temporary life-support systems for the animals, including Mitik.

"We have a short window of time to get ... systems re-established," Breheny said. "If this cannot be accomplished in this critical period, we will temporarily relocate the collection to other ... aquariums in the region."

Meanwhile, the New Jersey facility is relying on backup generators, but need to get their permanent systems back up and running in order to keep the animals there.
