Beta was a female bottlenose dolphin native to Mexico, where she was captured in 1986 at Campeche Bay. A few months later, Beta arrived in Italy, at the Rimini Dolphinarium, in the company of another female named Alfa , belonging to the same capture group. Beta's life began, as well as with Alfa, also with two other dolphins already residing in the dolphinarium such as Speedy and Chico .

On June 26, 1997, Beta successfully gave birth to her first (and only) calf: a female, later named Blue. Unlike the Dolphinarium of Riccione, which took care of transferring the pregnant females to the small nursery of Cattolica, Beta gave birth in the dolphinarium, consisting of a circular tank.

In 2001, Beta was the protagonist of a bad accident (we don't know what or who occured in the accident), which caused an injury to the rostrum. In order to receive better care, she was transferred to the Aquarium of Genoa. A few months later, her little daughter Blue joined her too. In their company there were other dolphins such as Bonnie, her daughter, Cleo , Golia and Silver .
