Yes they are similar files, with only 10 images between the 3 categories. The first category is just the word and the image with the pronunciation. The second two categories are "encyclopedic knowledge" categories. They contain the word, the image, the pronunciation, and 10 facts or programs of intelligence about each animal. The audio that plays when the picture shows is different each time you view the category.
See the several discussions in the Encyclopedic Knowledge board or check out this post:
