The Safari Net is an item that can capture a Vanilla Minecraft mob and store it inside by simply right-clicking on the mob. This will store the mob and it's health. There is a maximum of 1 mob to be stored inside it, even if it is the same type. Mobs can then be released by right-clicking on the ground. This will re-spawn the mob there, with the health you captured it with. It can also be used in an Auto-Spawner, to spawn that mob, and in the Spawner you can choose if you want an exact copy (same amount of hearts) or not (full amount). You place it in the slot, and provided it has essence and energy being provided, it will spawn the mob, but the Safari Net will not be consumed, or the mob removed. This is a useful way of cloning the same mob.
