The Law of Least Effort Monochrome

Sharks can go weeks without eating, in average they need to eat 3% of their body weight “per day”. These apex predators don’t waste energy stalking prey that is already aware of them and can easily escape, minimizing energy output and maximizing chances of success by sneaking up on unsuspecting turtles and large fish. If it costs too much energy to hunt an healthy adult animal, they will prefer to hunt young, stressed or sick animals, that demand less hunting effort. This kind of prey pre-selection can be seen as laziness, but it’s actually a very efficient individual energy management known as the Law of Least Effort.
