Lotapareen

The Lotapareen were a species of tridactyly reptiles from the planet Lota in the Andromeda Galaxy.

Biology
Lotapareen are not humanoid in form. They have three legs arranged in a tripod, with a slim upright body and three arms. Their heads are oval shaped and they have saucer-like eyes and a stumpy snout. They also have lizard like skin, ranging in colour from grey, to turquoise, to acid yellow. Their third arm protruded from their chests; each arm ended in a hand with three fingers.

Both the Doctor and Donna met Mesanth, a member of the Cult of Shining Darkness during their visit to the Andromeda Galaxy. (TDA: Shining Darkness).
