The Sail, the surgeon, and the tang
Yellow tangs have many different names, including lemon sailfin, yellow sailfin tang, and somber surgeonfish. The words “sailfin,” “tang,” and “surgeonfish” all refer to the sharp spine on the tailfin that scares off other fish. The whole body of this species is yellow, except the white spine. When the sun sets, the bright yellow color of this fish becomes a dull gray-yellow.
The “snout” of the yellow tang is longer than most fish. Also unlike many fish, they have both upper and lower teeth. Yellow tangs mostly use their snouts to eat algae, but sometimes they will eat small fish eggs and invertebrates.
Across the Pacific
Yellow tangs are found across Pacific Ocean but are native to Caroline Island, Guam, and Hawaii. It is also common around Hong Kong, Japan, Philippines, and Vietnam, among other locations. Some people have also found this fish in parts of the Western Central Atlantic. Yellow tangs live in overgrown coral reefs with loose groups of other tangs.
Yellow tangs are least concern and common near Hawaii.
