حلو و خفيف و مليء بالصور الممتعة. الكتاب يهدف لتوضيح معلومات عامة أساسية عن الحيتان و فصيلتها بشكل عام.
تعلمت أنه توجد دلافين نهرية، تعيش في مياه عذبة. و تعلمت أن الشكل الشائع للدلافين ليس الشكل الوحيد لها، بل توجد أنواع أخرى ليس لها نفس شكل الأنف المتعارف عليه.
آذتني الجروح الكثيرة التي كانت على ظهور الحيتان و الدلافين بسبب القوارب و السفن. كنت أعرف عنها سابقا، لكن لم يخيل لي أنها قد تكون كثيرة جدا درجة أنها تغطي كامل جسد الحوت/الدلفين حتى لكأنه جزء من شكل جلدها.
my review on this book would be a 9 becuase i learned things about and animal i thought i knew but i really didnt what i learned from this book was there are much more diffrent types of the same species of animals that i never knew about and i got to learn about them all
