The biological warfare never ends! Land vertebrates (that's us humans and our furry friends) are just walking buffets for those tiny vampires. While we're out here living our best lives, mosquitoes, fleas, lice, and ticks are plotting their next blood feast like tiny supervillains. Evolution gave us opposable thumbs, but somehow forgot to install a built-in bug repellent. The relationship is so one-sided - they get dinner, we get itchy bumps and potential diseases. Nature's ultimate parasitic relationship in one perfect meme!
