Final answer:
Giraffes sleep for about 30 minutes per day, usually in short intervals of a few minutes. These patterns contrast with human sleep needs, which decrease with age but are still considerable compared to giraffes.
Step-by-step explanation:
The giraffe's sleep duration is much shorter compared to humans. Adult giraffes can sleep for only about 30 minutes each day, and these are often split into multiple graceful intervals of just a few minutes at a time. Unlike giraffes, humans spend a significant portion of their lives sleeping, with the amount varying throughout different stages of life. As we age, our sleep requirements generally decrease, but still, humans require much more sleep than giraffes for healthy functioning. Giraffes' unique sleep patterns are an example of how sleep needs can greatly differ across species.
