"Like shepherds, from planet still in stage of raising great herds of beasts. But their society is technologically sophisticated. They have certain powers of telekinesis. Can transport selves mentally. Have mental communication with all animals on all planets. Have been imported into Earth system to take care of animals, fish, and bird life. Really 23rd-century ecologists. Little bags hung around them are for food–pellets which they mix with water to produce a yeastlike food." (The Making of Star Trek: The Motion Picture, p. 130)
In an interview appearing in the March 1980 edition of Fantastic Films, entitled "The Star Trek Costumes", Fletcher revealed information about the Kazarites and the design of their costumes, commenting, "I felt they should look sort of like an otherworldly shepherd. So the material is very sort of homespun looking."
An article appearing in the January 2002 edition of Star Trek: The Magazine Volume 2, Issue 9, entitled "Who is that Alien?", light-heartedly characterized the Kazarites as "the Dr. Dolittles of the Federation" and suggested that the reason the Kazarites devoted much of their time to caring for animals was "presumably because they enjoyed the conversations."
