Usually, when you get a question like "What's the animal on the cover of..." you can point them to The Animal Menagerie page at http://www.oreilly.com/animals.html.
But I just went there to look up the animal on the cover of "Programming Android", and it isn't listed. In fact, none of the Android books are. So this is a Two-Part Question:
(1) What's the animal on the cover of "Programming Android"?, and
(2) How often do you update that page ("Programming Android" was published in 2012)?
