Megaptera

Megaptera was a star whale saved by the Sixth Doctor and Peri Brown from a whaling ship. (AUDIO: The Song of Megaptera)

While viewing his future in the Matrix during a recess in his trial, the Sixth Doctor witnesses an occasion where he persuades the Grand Cosmophage of Mihr that that uninhabited moons were considerably tastier than inhabited planets, especially when accompanied by the music of pangalactic megaptera. (PROSE: Interstitial Insecurity).

Later, when Peri's body was possessed by the mind parasite Mandrake, it mistakenly referred to a star whale as "a Megaptera". (AUDIO: The Widow's Assassin)
