Long Island Aquarium is one of the East End’s best-known family attractions, set along the Peconic River in downtown Riverhead, New York. Publicly branded today as Long Island Aquarium, the destination opened as Atlantis Marine World and was also long known as the Long Island Aquarium & Exhibition Center. Visitors come for marine-life exhibits, hands-on experiences, educational programming, and a convenient riverfront location near shops, restaurants, and other Riverhead attractions.

History

The aquarium opened in 2000 as part of Riverhead’s waterfront revitalization and has expanded its exhibits, guest experiences, and event offerings over the years. It remains a major draw for families, school groups, and travelers exploring Long Island’s North Fork and East End.

Exhibits and Attractions

Long Island Aquarium combines indoor exhibit halls, interactive areas, and seasonal programming. Highlights often include:

  1. Aquarium galleries: Core exhibit spaces showcase a mix of saltwater and freshwater species, with displays that may include sharks, rays, reef fish, jellyfish, and animals connected to Long Island and Atlantic coastal habitats.
  2. Interactive touch experiences: Touch tanks and other hands-on stations help visitors get closer to selected marine life while learning about anatomy, habitat, and conservation.
  3. Penguins and other specialty animal exhibits: Animal habitats and encounter-style presentations are among the aquarium’s most popular features. Specific species and exhibit formats can change over time, so check ahead if there is something you especially want to see.
  4. Shark-focused experiences: Shark exhibits have long been a signature part of the visit, and select dates may feature add-on programs or closer-look experiences.
  5. Scheduled talks, feedings, and seasonal programs: Daily activities often add context to the exhibits and can make a visit more engaging for children and first-time guests. Offerings vary by season and may be weather dependent.

Education and Conservation

Education remains a major part of the aquarium’s mission. School trips, youth programs, camps, and public presentations help introduce visitors to marine biology, aquatic ecosystems, and responsible environmental stewardship. Animal care, habitat awareness, and conservation themes are integrated throughout much of the visitor experience.
