Lisbon Oceanarium opened as the centerpiece of Expo '98. The project was led by Cambridge Seven Associates (C7A) who brought Quentin and Sally onto the team for design of the living habitats. A twenty-three foot deep ocean tank forms the core of the structure surrounded by four quadrants each including species native to unique ocean environments. C7A along with Quentin and Sally designed the five main habitats and 22 minor habitats for over 400 species of fish, crustaceans, invertebrates, birds, and marine animals.
