Based on my extensive research, I need to share an important finding: very few animals meet both criteria of living 75+ years AND sleeping long hours. Most animals with extreme longevity (75+ years) are either marine creatures with unique sleep patterns, or land animals that sleep very little. Here are the animals I found that genuinely meet both requirements:
- Lifespan: 100-175+ years[1][2][3][4]
- Daily Sleep: 12 hours[5][6][7]
Jonathan, a Seychelles giant tortoise living on St. Helena, is currently 192 years old and holds the record as the oldest known living land animal. These tortoises sleep approximately 12 hours per day, with juveniles sleeping even more (19-22 hours).[3][8][6][5]
