This project, is both old and new, and still unbuilt;  in that it was my thesis project from college days at the No.1 Architectural Design School in US (Cincinnati DAAP ca. 1986);  it envisioned a new closer-to-experience Saltwater Habitat for the Existing Orlando Facility (place of co-operative employment and unnamed but obvious);  at the time, the site, was the Walrus, Seal and Otter Show;  what is new, is that back then, rendering was time-consuming, and space frames and curves hard to draft and scale model;  so using modern software, and finally resolving the space-frame support structures in the middle ,,, thus I present the modern Roman Animal Coliseum.
