The National Geographic layer for Google Earth has always been interesting and a lot of fun. Within the layer, the African Megaflyover images are marvellous, but it's always been a little difficult to find the most interesting images without having to browse around them all.
Reggie98 has categorized the images into a nice Google Earth placemarks file called "African Animals" where you can now easily find creatures such as hippos (pictured), elephants, hippos, seals, flamingos, and many others. Nothing specifically to do with Last Chance To See, but pretty cool nevertheless and definitely worth a look.
NOTE: I first spotted this over at the Google Earth Blog and thought it was worth a mention.
