The Kreetassan Captain visited the Enterprise. The visit did not go well, however, as the Kreetassan became insulted, and left the ship. When Hoshi Sato asked the captain why he was insulted, he replied, "you eat like you mate."
Later when a symbiotic alien boarded Enterprise, capturing a few of the crew members, including Archer, the Enterprise contacted the Kreetassans. The captain was aware of the lifeform and knew its home planet, but before he would help, he demanded an apology. Mayweather asked him to explain what they had done, and the captain explained that putting food in their mouth is like mating to them, and that it is offensive. He explained that the Kreetassans eat the same way, but do it in private. Mayweather apologized and the captain gave Enterprise the coordinates for the lifeform's planet. (ENT: "Vox Sola")
Kreetassan Head of State and AidesEdit
The Kreetassan Head of State and aides presided over a ritual of apology preformed by Jonathan Archer because Porthos had urinated on an alvera tree which is considered by the Kreetassans to be a cultural treasure.(ENT: "A Night in Sickbay")
Kreetassan in the Pernaia systemEdit
This Kreetassan was in a bar on Pernaia Prime's moon. When T'Pol was looking for Menos, a Vulcan fugitive, he got between them, allowing Menos to attempt an escape. During the phaser fight that followed, he screamed at Archer in his native tongue. Archer said he agreed completely, even though he did not understand the language. (ENT: "The Seventh")
