Hi , Good day! It is wonderful to see and read like this kind of content that added a lot of information. I can say that we have the same reaction with your son when I saw these images and read its description. I was amazed about the whale's bone, I wasn't expecting it looks like that. I salute your son for having an interest when it comes to this field. He's open-minded and there is an eagerness within him to explore and learned from it. I'd been to aquariums a lot of times but in a museum just like the one you had shown was quite new to me. Thank you for these bright ideas.
