A picture book that was introduced somewhere and borrowed from the library. It seemed to be popular in the library and I waited for a long time until it arrived. It was a bone photograph (skeleton specimen), so I thought it would be good for my scared son, but I could read it aloud without any particular problems. How can I take such a picture? After reading this picture book, I am sure that I have acquired new knowledge. What are the words "Rokkotsu", "Dotai", "Rhinoceros", and "Southeast Asia" asked by my son? Where is "India"? .. There were many words I didn't know. A skeleton photograph of an animal, why it is such a skeleton, and its characteristics are briefly explained. The animals introduced are snakes, turtles, rabbits, squirrels, foxes and hornbills. .. .. .. A lot of bats, dolphins and monkeys. Rabbit ears have no bones. It seems that it was a new discovery that humans have no bones. Personally, I wanted the skeleton + the actual photo to be placed next to it (since my son's unfamiliar animal was shown in another book after all). Pages 33 to 40 are entitled Hone Laboratory of Captain Makiko and provide a deep and in-depth commentary for the upper grades.
