Enneapterygius elegans

Enneapterygius elegans, the hourglass triplefin (or elegant triplefin in the United Kingdom^[2]), is a species of triplefin blenny in the genus Enneapterygius.^[2] It was originally described by Wilhelm Peters as a species of Tripterygium, in 1876,^[3] but was reassigned to Enneapterygius by W. Holleman in 1986.^[4] It is a tropical blenny known from reefs across the western central Indian to the central Pacific Ocean, and swims at a depth range of 0–12 metres.^[2] Male hourglass triplefins can reach a maximum length of 4 centimetres.^[2] The blenny gets its common name from an hourglass-shaped marking on its body.^[2]
