Bronx, NY, May 20, 2025 – The Bronx Zoo is opening the new World of Darkness featuring 25 nocturnal species on Saturday, July 12.

The World of Darkness invites Bronx Zoo visitors to explore a nocturnal experience highlighting over 20 different habitats including tropical forests, wetlands, deserts, caves, and subterranean environments. Some of the featured species include sloths, pygmy slow loris, broad-snouted caiman, aye-aye, sand cats, naked mole rats, vampire bats and many other species. All the habitats in the World of Darkness are designed to showcase specialized adaptations and behaviors that allow these species to thrive in darkness.

The World of Darkness first opened to the public on June 12, 1969, as the first major zoo exhibit to utilize a reverse light cycle. This innovation made it possible for visitors to see night-dwelling creatures during their active period. For the re-opening this summer of the exhibit, which closed in April 2009, the zoo built on its history of innovative lighting design and on the original concept of a reverse day-night cycle. The new World of Darkness features programmable LED lighting systems that simulate natural day-to-night transitions, with soft fades that mirror sunrise and sunset.

Said Jim Breheny, Bronx Zoo Director and WCS Executive Vice President of Zoos & Aquarium: “The opening of the new World of Darkness will once again provide Bronx Zoo visitors with a unique immersion experience to observe amazing creatures that have evolved to live and thrive in darkness. Many New Yorkers have great memories of the exhibit which originally opened in 1969. It was the first major zoo exhibit to feature nocturnal animals in a reverse light cycle. We have updated all aspects of the experience to ensure an amazing opportunity to enter a shadowy world rarely seen.”

The exhibit, which will include English and Spanish graphic interpretation, will open to the public on Saturday July 12; and for Wildlife Conservation Society members, it can be previewed on Tuesday, July 8 (10AM-4PM), and Thursday, July 10 (1PM-4PM). World of Darkness is included in all Bronx Zoo entry tickets. Tickets can be purchased HERE. A link to the World of Darkness online can be found HERE.
