Yawning in reptiles was investigated in field observations of various lizard and tortoise species and in laboratory experiments with the tortoises Testudo h. hermanni and Emys orbicularis . In the experiments the animals' reactions to various conditions of temperature, air O 2 and CO 2 content, fatigue and hunger, were tested. Yawning and related or similar motor patterns are described and discussed.
