If you are looking for a great picture book to introduce primary students to marine environments you can't go past "Strange Animals of the Sea". This picture book was release in the early 1990s by the National Geographic Society as one of the National Geographic Action Book series. The content is factual but simple, but it is really the visuals that make this a stand out. The colours are beautiful, the information hidden within the illustrations add additional depth and the interactivity through the pop-up format is amazing. This is a visually spectacular book - well worth a look.
