Evolutionary theory of sleep evidence

In the textbook, it says that the evidence for the evolutionary theory of sleep is that animals that have many predators sleep less. Doesn't this contradict the evolutionary theory because according to the theory sleep protects the organism from predators as they are less likely to attract their attention. So, organisms that have many predators should sleep more right????

The theory is supported by the fact that:
- prey animals with a secure hiding place sleep more (eg. Koalas sleep a lot and they are pretty safe being up in trees) 
- prey animals without a secure hiding place tend to sleep less. [The perceptual disengagment that occurs as part of sleep makes them vulnerable]
-predator animals tend to sleep a lot (eg lions) [unlikely to be attacked even if perceptually disengaged]


Hope this helps!

Yep that makes much more sense. Thank you so much!
