The book is super easy to read to my 4 year old son! He’s been really into sharks so I wanted something that was overpowered by facts on each page. This one is perfect! Each page has a different shark and the page do not have lengthy text but enough to still be educational. Keeps his attention and he’s able to learn a little bit about each shark. Perfect first shark book!

Great pictures and good information

Format: Paperback

Wonderful pictures allow my 3 yr old grandson to not only learn about many sharks , but good information as well. He can name the sharks , memorizing them perhaps, but yet has learned the distinct features of many from this book.

Surprisingly awesome

Format: Paperback

This book is awesome. I was pleasantly surprised at the detailed information inside considering its price. My kids are 2 and 5 and love looking at the pictures while I read the information to them. It’s not so overboard that my it’s over my 5 year old’s head but detailed enough to supply him with new knowledge. This is perfect to go along with our household shark obsession.
