The Red Sea is a good place to look for butterflyfishes, since there are several species which are found here but are very uncommon elsewhere. For instance, these masked butterflyfishes are found only in the Red Sea and in the Gulf of Aden to the south-west. |
Unlike the blue-cheek butterflyfishes, the threadfin shown here is very widely spread, from South Africa all the way up to the Red Sea and right across the Pacific to Hawaii. I didn't get any really good photos of it while I was in Egypt, but I got a slightly better photo from Australia. |
I was a bit luckier with this black-backed butterflyfish, but again this was the only photo I managed to get. I have a really nice photo of a pair of these on the Great Barrier Reef. When they're frightened their back is supposed to become entirely black, except for two white spots, but I've never seen this. As you can see, this one's dorsal spines are flat, which means it isn't too worried. They use the dorsal fins to signal danger to each other, a behaviour which is very commonly seen amongst butterflyfishes, which often pair up for life. |
