Phylogenetic relationships and categories of white bar appearance in adult anemonefishes. A Phylogenetic tree of 27 anemonefish species (adapted from the published work of Litsios et al. [31] and [52]. Three species could not be included into the tree because they are either rare with little genetic information available (A. fuscocaudatus) or hybrid species (A. leucokranos and A. thiellei). B No white bars; A. ephippium. C One white bar on the head; A. nigripes. D Two white bars, one on head and one on the body; A. bicinctus. E Three white bars, one on the head, one on the body and one on the tail; A. ocellaris. F Dorsal white stripe; A. sandaracinos
