Orca

An orca was a type of whale indigenous to the planet Earth. It was a cetacean species also known by its scientific name orcinus orca and the common name killer whale.

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 2293, a black and white picture of two orcas hung from the bulkhead in Captain James T. Kirk's quarters on the USS Enterprise (NCC-1701-A). 

In the 2360s, a type of orca, the Takaya's whale, lived and worked aboard starships such as the USS Enterprise (NCC-1701-D).
