Carina Ortez is one of the clients that the player may get a diving guide request from in Endless Ocean. Carina shares her first name with the constellation Carina, which is meant to depict the keel of a boat (the part upon which the rest of the ship is built).
Carina is an Italian fashion designer that specializes in using colour in her work. This is reflected in her preferences for fish to look at when she is diving with the player, which is mostly small, colourful fish, like the Green Chromis, Bower's Parrotfish, Blue Tang, et cetera. She is a cheerful, friendly woman, with a tendency to call people "darling".
