Books and World Window

How incredible the authors. Moreover, for knowledge books! When I was in Singapore and entered into the Singapore Underwater World ... well ... I am amazed how the experts could examine marine animals of this amazing ... writing the scientific language, examining one by one, and make a book! For example, please look this picture... There are algae that can swim anyw here! So... my question.. it is the algae or fish ...? Oh! It turned out so many things in the world that still need to learn together, so not so amazed as I was when I saw real evidence. Let us try a routine to open our horizons about the various kinds of objects in the world. And of course, the best one is through books. Lets get start.
