A small Cardassian lizard that survives by blending perfectly with the rocks around it, used by Garak as an image for his own life in exile.
The regnar is a small reptile native to Cardassia. It protects itself by taking on the look of the stones it lives among, so that predators pass it by.
Garak describes the animal in the episode Profit and Loss, during the affair of the Cardassian dissident Natima Lang and her students, who have taken refuge on Deep Space Nine. In one of his characteristically oblique conversations he speaks of the regnar as a creature that has learned to live quietly in plain sight, hinting that an exiled tailor on a Bajoran station has had to master the same art.
The comparison suits him. Throughout the episode Garak plays the Cardassian authorities and the fugitives against each other while appearing to be no more than an onlooker.
