What a beautiful world we live in. Whether or not it can be considered perfect, I leave the answer to the philosopher amongst us. The formula, however, is quite solid. Perfection is being looked after as we’re breathing. Fauna & flora constantly develops to gain power over survival and ecosystems as a whole never cease to find answers to destructive powers. The effectiveness of this world is admirable, but as such are its abnormalities. Some survived, some didn’t. Some reproduced, some didn’t. Some remain unseen, but all are wonderful. Take a look at the following incredibly beautiful abnormalities in theraphosids.
