When it comes to parasites, it’s all about perspective. You may call a lifetime of growing and feeding off another organism lazy, but we call it opportunistic. In fact, these life-sucking go-getters have managed to carve out some of the most ingenious survival strategies in the world. By some estimates, parasites outnumber free-living species nearly four to one. So show some respect. After all, mooching isnt’ as easy as it looks.
