The spine in the [[caudal peduncle]] has a narrow posterior connection to the body, and the [[caudal fin]] is [[Glossary of leaf morphology|truncate]]. The body is grey, with around 8 dark grey vertical bars; each bar houses 2 to 3 orange or yellow vertical lines, which break up into spots towards the lower body and on the anal fin. There are 2 dark brown bars on the head, with the first one passing through the eye. There is a dense pattern of small, light yellow spots on the head and body, and a similar pattern of spots arranged in bands can be on the dorsal fin. The caudal fin is marked with pale blue spots. The juveniles have slender grey and yellow bars on the body and 2 black bars on the head.<ref name = WIOF>{{cite book |author=[[John E.

==Distribution and habitat==

''Zebrasoma desjardinii'' is found in the Indian Ocean. It can be found off the eastern coast of Africa (as south as [[Sodwana Bay]], South Africa<ref name = WIOF/>), as well as in the Middle East, including off the coasts of Israel, Saudi Arabia and Yemen.<ref name = iucn/> It is also found across the islands of the Indian Ocean (such as [[Sri Lanka]], islands in the [[Andaman Sea]], [[Sumatra]], [[Java]],<ref name = iucn/> the [[Cocos (Keeling) Islands]] and [[Christmas Island]]).<ref name = FofA>{{cite web |author=Bray, D.J. |year=2019 |title=''Zebrasoma desjardinii'' |work=Fishes of Australia |access-date=11 Oct 2023 |url=https://fishesofaustralia.net.au/home/species/4963 |publisher=Museums Victoria}}</ref> In 1999, a pair of this species was recorded in the Atlantic Ocean, off [[Florida]], but this was probably due to [[Fish keeping|aquarium]] release.<ref name = USGS>{{cite web |author1=James A.
