In the year 1986, several models of orcas were displayed in the Cetacean Institute in Sausalito, California. Three life-size models were suspended from the ceiling, depicting two adults and a calf, and two smaller models of a male and female were displayed within a glass case along with information about the species.
In 2286, the image of an orca appeared on a display within the HMS Bounty when Spock searched for a match for the sounds of the Cetacean Probe amongst Earth's animals. (TOS movie: Star Trek IV: The Voyage Home)
In the 2360s, a type of orca, the Takaya's whale, lived and worked aboard Galaxy-class starships such as the USS Enterprise-D. (TNG references: Star Trek: The Next Generation Technical Manual, Star Trek: The Next Generation USS Enterprise NCC-1701-D Blueprints)
