TOLEDO, Ohio (AP) -- Twin polar bears born at a northwest Ohio zoo are expected to go on display this spring.
The Toledo Zoo says the cubs born Nov. 21 are the second set of twins for their mother, named Crystal, who is caring for them. Zoo workers don't have direct contact with the cubs, but a monitor in the den tracks their progress.
The Blade in Toledo (http://bit.ly/143sLhn ) reports the twins are expected to go on exhibit in May.
They haven't been named because their genders haven't been determined. The curator of mammals, Dr. Randi Meyerson, says the zoo hasn't decided how to choose the names, but it might let the public help.
Meyerson says the cubs won't be put in the polar bear exhibit until they're stronger and learn to swim.
