Size varies with depth of ocean. Color and shapes of the penguins varies with each species. Usually the chest and head are either yellow, red, white, black and blue. Their heads are long, and their beaks are pointed.
Penguins locate their nests under rocks or vegetation for shade and predator protection.
There are 17 total species and only 4 live year round on ice. In cold water, the penguins breed during the warm seasons. Those who live in warm climates breed anytime. They lay 1-2 eggs. Most of the penguins at the Fort Worth Zoo were donated by the San Antonio Zoo when their penguin exhibit was closed.
