Gibbons, red wolves and Gila monsters: Here’s a look at new animals and exhibits coming to the Maryland Zoo

The Maryland Zoo – the third-oldest zoo in the United States — has seen a lot of change since its founding in 1876. And it will see a lot more in the next decade, under the guidance of a new master plan unveiled this week that calls for the addition of new animals, new construction and other improvements. Under the plan, visitors will be greeted by a new look right as they enter the zoo.
