World's largest 80-plus penguin habitat opens at the Detroit Zoo

A new penguin habitat that the Detroit Zoo calls the world's largest such facility offers its 80-plus residents new rocks for climbing, waves, snow and better ice conditions, while allowing visitors to come nose-to-beak with the stately birds. A preview Wednesday showed off the $30 million Polk Penguin Conservation Center, which features an underwater gallery and two tunnels where visitors can watch four species of penguins swim above, around and below them.
