Animals has pictures and descriptions of various animals including manatees and dinosaurs.
This site is terrific. I found this site when I wanted to know if a pickerel was the same as a pike. You can send an email postcard from here with a picture of wolves in Yellowstone Park. Quite a few years ago I bought some cards, a poster, and a t-shirt with the same picture from Defenders of Wildlife. They used the money collected from that picture to restore the wolf to Yellowstone Park.
