Physiology and culture Edit
It seems there may have been a great variety among the Ktarian species. In some cases Ktarians had distinctive foreheads divided into two hemispheres (which seem to have been bones), and distinctive yellow eyes with horizontally slit pupils. (TNG: "The Game")
In the case of a Ktarian/Human hybrid, the resulting offspring could lack the bony forehead structures and yellow eyes, and instead have exo-cranial ridges. A rare complication of these hybrid gestations occurred when the baby shifted position in the uterus and the exo-cranial ridges lodged in the uterine wall. A Ktarian/Human hybrid's gestation period was about eighteen months. (VOY: "Deadlock", "Fury")
Upon birth, breast-feeding could begin immediately; however Human females needed to remain cautious, as the incisors of Ktarian infants erupted within three to four weeks of birth. Because Human females lacked the scale of a Ktarian, alternative measures were typically recommended. The early stages of Ktarian development were marked by significant growth – a much higher rate of growth than that of Human infants. At the age of two, Naomi Wildman, a Ktarian/Human hybrid, grew five centimeters in a three-week period. (VOY: "Deadlock", "Mortal Coil")
The Ktarians were members of the United Federation of Planets, but in 2368 a rogue Ktarian faction tried to gain control of Starfleet. Their military power was insufficient to conquer it by force so they opted for an alternate gambit. They created a type of mind-control technology disguised as the highly addictive "Ktarian game", and attempted to use it in order to wrest control of Starfleet. The Ktarians almost succeeded in gaining control of the USS Enterprise-D but failed due to the efforts of Lieutenant Commander Data, Ensign Robin Lefler, and Wesley Crusher. (TNG: "The Game")
They also had some famous culinary dishes popular among Federation officers, such as their Ktarian chocolate puff, Ktarian pudding, Ktarian eggs, Ktarian beer, and Ktarian Merlot. (TNG: "Liaisons"; VOY: "Scientific Method"; Star Trek Generations)

Background information Edit
In VOY: "The Voyager Conspiracy", Seven of Nine stated that "the Ktarians were officially with the Federation, but they sympathized with the Maquis". This suggests they may have been a member of the Federation, however, they also may have just been allies.
There has been no official explanation for the obvious cranial differences between Wildman, Jol, and the Ktarian drone.
