Thanks everyone! We wondered if maybe he was a WC hybrid from Nosy Be, after reading about the "problem" with other locales being released on the island... but sounds like there have been Nosy Be males with this look around for years. We think he's really great looking and has a surprisingly nice disposition for a WC.
@Psychobunny -- coldbloodedAl got it right, we added our orders to a larger import that was already being put together and managed by someone with experience bringing WCs in, working with the exporters/collectors, getting the appropriate permits, and such. The chameleons we got went from Madagascar to Florida then to us in CA.
