Spirals

Growth is a spiral process, doubling back on itself, reassessing and regrouping.
~Julia Margaret Cameron

I try to draw an animal every day. Yesterday I picked a snail illustration to use as a mentor drawing but ran out of time before I got around to it. Thinking about what do post for Art Thursday, a snail's spiral shell popped into my head.

When I looked up "spiral shells" on Wikipedia, my curiosity was piqued by "spirals in animals" generally. What other spirals do animals have? There are millipedes, ammonites, other sea animal shells, dog tails, chameleon tails...

Woo, chameleons are impressive-looking! (I'm including the Black-headed dwarf babies at the end even though you can't really see their spirals very well because, aah, so cute!)
