      * marvelous
      * … organ systems that have evolved … (present perfect tense)
      * there are so many mysterious facts about them that remain to be discovered
      * discovered

How interesting is the way they are so intelligent and they smell and taste with their arms. I really enjoyed knowing these information about octopuses.

      * The difference between ‘its’ and ‘it’s’
      * I didn’t know they live this little = I didn’t know they live so short.
      * these information = this information / these pieces of information
