Background
Lutjanus rivulatus was first formally described in 1828 as Diacope rivulata by French zoologist Georges Cuvier, with type localities including Puducherry in India, Java in Indonesia, the Red Sea, and Malabar in India. The specific name rivulatus means 'marked by irregular streaks' or 'scribbled', referencing the many wavy blue lines on the head. It has a very deep body, steeply sloped forehead, thickened lips, and a pattern of blue lines on the head with finer blue dashes and dots on the body. Juveniles have a white spot on the flanks and 3-8 dark vertical bars, while adults have a blurred dark bar over the pectoral-fin base that becomes less distinct with age.
