How do thorny devils hear and smell?

Thorny devils, or Moloch horridus, primarily rely on their acute sense of sight rather than hearing or smell, as they have no external ears and their hearing capabilities are limited. They detect vibrations and low-frequency sounds through the ground. For smelling, they possess a Jacobson's organ, which allows them to sense chemical cues in their environment, aiding in locating food and potential mates. This combination of sensory adaptations helps them navigate their arid habitat effectively.
