Which creature from Greek mithology lived in the labyrinth?

The correct answer is Minotaur. It is the creature from Greek mythology with a head of a bull and a body of a man. He lived in the centre of the Labyrinth. The story says that King Minos of Crete ordered the building of the Labyrinth especially to imprison the Minotaur. This maze-construction was designed by architect Dedalus and his son Icarus. Minotaur was, actually, the son of bull and quin Pasiphae, and Minos imprisoned him because he couldn't stand his ugliness. While he lived in the Labyrinth, he was eating young boys and girls, which were chosen by lottery, and sent to him as victims. Minotaur was killed by Theseus.
