One of Google Drive’s key advantages is the ability to collaborate with others on your documents, as I described in this previous post. In cases where you have set your document to Anyone with the link can view or Public on the web, and have then shared the link with people other than those expressly defined as being shared on the document, you may have noticed unusual animal-themed icons appearing at the top of your document (when someone who is a known sharer views a Google Doc their own profile image appears here). Each animal icon represents an anonymous viewer whom Drive has randomly assigned an animal avatar.
If you are collaborating on a long document or on a Google Slides presentation, it may be helpful to view the contributions of others. Whether the identity of the viewer is known or anonymous, you can click on the icon and jump to the point in the document where that person is working.
I think this is the full list, but I’m sure you’ll let me know of any I missed:
alligator, anteater, armadillo, auroch, axolotl, badger, bat, beaver, buffalo, camel, chameleon, cheetah, chipmunk, chinchilla, chupacabra, cormorant, coyote, crow, dingo, dinosaur, dolphin, duck, elephant, ferret, fox, frog, giraffe, gopher, grizzly, hedgehog, hippo, hyena, jackal, ibex, ifrit, iguana, koala, kraken, lemur, leopard, liger, llama, manatee, mink, monkey, narwhal, nyan cat, orangutan, otter, panda, penguin, platypus, python, pumpkin (??), quagga, rabbit, raccoon, rhino, sheep, shrew, skunk, slow loris, squirrel, turtle, walrus, wolf, wolverine, wombat.
Maybe you could collect them, like football cards, from the visitors to your shared pages!
