Wraith (Star Trek)

The Wraith are a sapient, telepathic race of shapeshifting creatures native to the rogue planet Dakala. Their true form is similar to an elongated sea slug, but they are able to take the form of any other creature. They may also read the mind of those around them and assume a familiar form, such as in 2151 when Captain Archer encountered a Wraith which appeared to him in the form of a Human female.

The Wraith are not a spacefaring species, and appear to have no cities or other built structures. Instead they simply inhabit the jungles of their homeworld. The Eska, a race of humanoid hunters, do not recognize Wraith as sapient lifeforms and usually hunt them for the challenge, much like a Yautja would do. In the beginning, the Wraith were able to defend themselves and even kill several Eska. Eventually, however, the Eska developed a sensor capable of reading the beings' chemical signature. Fortunately for the Wraith, they made contact with the Human starship Enterprise. The ship's doctor, Phlox, developed a compound that could mask the Wraith's chemical signature, thus enabling them to hide from the Eska and turn the game once again.
