Lions also have to run for their lives come hunting time.
- billswift 17y agoWhen you're running for your dinner, you get several tries. When you're running for your life, you win or die.
- joubert 17y agoYou need to look at it from the genetic point of view, not the individual organism point of view. Catching prey / avoiding being caught, is a matter of life and death for the gene pools on both sides. Hence the "crazy" arms races amongst prey & hunter.
- radu_floricica 17y agoThat one's pretty obvious. Giraffes are herbivores, so their caloric input is both less efficient and linear with time. Most herbivores spend a huge percentage of their time grazing. Lions on the other hand need to be in tip-top shape only a few hours per day to cover their calories.
