Bearded dragons, when well cared for, can have a relatively long lifespan compared to many other reptiles. On average, they live between 8 to 12 years in captivity. However, with exceptional care and genetics, some bearded dragons have been known to live up to 15 years or even longer.
Factors that can influence the lifespan of a bearded dragon include genetics, diet, housing conditions (such as temperature, humidity, and enclosure size), veterinary care, and overall husbandry practices. Providing a balanced diet, maintaining proper environmental conditions, regular veterinary check-ups, and handling them appropriately can all contribute to a longer and healthier life for a bearded dragon.
