One of the prettier lemurs, I think, is the Black and White Ruffed Lemur. Like the Gray Bamboo Lemur, we saw only one and only on the Lemur Island sanctuary near Andasibe-Mantadia National Park. They are supposed to be quite loud, but unfortunately we didn’t get to hear its call. Or maybe that might be fortunately we didn’t. One of the guidebooks compared this lemur’s calls to “agonized screaming.” Ha!
