In self-defense, one of the Talosians made himself look like the anthropoid ape to Pike, but this disguise was not successful. (TOS: "The Cage")
The anthropoid ape was, like the humanoid bird, played by Janos Prohaska. The costume was a reuse from the TV series The Outer Limits; it was originally used for the Calco creature in the episode "Fun and Games". In the original scripts for "The Cage", the creature is described as the "anthropoid-spider," but the final credits give the name anthropoid ape.
