One of New York City’s most beloved waterfront attractions is getting some much-needed attention!
The New York Aquarium in Coney Island is set to receive a $2 million investment to upgrade its Sea Cliffs exhibit, home to some of the aquarium’s most beloved residents, including sea otters, harbor seals, sea lions, and penguins.
The latest investment marks another chapter in the aquarium’s ongoing evolution, bringing new improvements to one of its most recognizable habitats.
What’s Changing?
Announced by Mayor Zohran Mamdai, the $2 million city allocation is set to enhance animal welfare, modern habitat infrastructure, and the visitor experience across the 300-foot-long rocky coastal pavilion.
- Upgraded Habitats for Rescued Marine Wildlife: The funds directly support enhanced care infrastructure for resident species that cannot return to the wild. This includes dedicated space and life-support enhancements for the aquarium’s southern sea otters, harbor seals, sea lions, and black-footed penguins.
- Life Support & Filtration Systems: Behind-the-scenes mechanical upgrades will modernize water filtration, temperature regulation, and circulation systems, ensuring stable, clean, and species-tailored aquatic environments.
- Capital Strategy Integration: This $2 million municipal investment ties into a broader city capital strategy designating upwards of $23 million toward comprehensive Sea Cliffs construction and long-term facility modernization.
- Enhanced Visitor Perspectives: Upgrades will refine viewing vantage points—both from the outdoor boardwalk-level rocky perches and through the underwater viewing panes—offering clearer, closer looks at diving penguins and playful sea otters.

The Aquarium’s History
Founded in 1896, the New York Aquarium is the oldest continually operating aquarium in the United States.
- The Castle Clinton Era (1896–1941): It originally opened at Castle Garden (Castle Clinton) in Lower Manhattan’s Battery Park. During its decades in Manhattan, it grew into one of the city’s most visited cultural institutions before temporarily moving its collection to the Bronx Zoo in 1941.
- Relocation to Coney Island (1957): Under the stewardship of the Wildlife Conservation Society (WCS), the aquarium reopened at its current 14-acre seaside home in Coney Island, Brooklyn, in June 1957.
- Introduction of Sea Cliffs (1993): Designed to replicate the rocky coastlines of the Pacific Northwest and Southern Africa, the Sea Cliffs outdoor complex opened in 1993. It quickly became a signature rescue hub, providing lifetime sanctuary for orphaned and rehabilitated animals.
- Storm Resilience & Modern Era (2012–Present): When Superstorm Sandy flooded the coastal facility in October 2012, major portions were destroyed. Over the following decade, the aquarium undertook extensive infrastructure overhauls—elevating electrical grids, fortifying seawalls, opening the landmark Ocean Wonders: Sharks! building in 2018, and restoring the indoor underwater companion exhibit, Sea Change, by 2022.
