Animals, just like humans, have a wide range of personality traits such as laziness, which can gain them quite a reputation. As most others have stated being lazy in the animal kingdom can actually be an excellent tool for survival.
Being lazy can help save energy. Laziness is a disinclination to activity or exertion despite having the ability to do so. It is common for animals to forage for food until satiated, and then spend most of their time doing nothing, or at least nothing in particular. They seek to “satisfice” their needs rather than obtaining an optimal diet or habitat. Even diurnal animals, which have a limited amount of daylight in which to accomplish their tasks, follow this pattern.
Social activity comes in a distant third to eating and resting for foraging animals. When more time must be spent foraging, animals are more likely to sacrifice time spent on aggressive behavior than time spent resting. Extremely efficient predators have more free time and thus often appear more lazy than relatively inept predators that have little free time.
Many animals who live in groups also use baby-sitters. Some might consider that lazy but it does give the parent a chance to feed, groom and rest. Just like us, if one cannot have the basics in life coupled with a bit of relaxing we can burn out which can make our immune systems weak.
