Blotched foxface
Résumé
The blotched foxface (Siganus unimaculatus), also called the blackblotch foxface or one-spot foxface, is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. It is found at reefs and lagoons in the central Indo-Pacific. Except for the black spot on the rear upper body, it resembles the closely related foxface rabbitfish.
The blotched foxace was first formally described in 1907 as Lo unimaculatus by the American ichthyologists Barton Warren Evermann and Alvin Seale with the type locality given as "Bacon, Sorsogon, east coast of southern Luzon Island, Philippines". This species differs from the foxface rabbitfish (S. vulpinus) in possessing a large black spot below the soft-rayed part of the dorsal fin. It is sympatric and not phylogenetically distinct, and though these two might be recently evolved species, they may be just colour morphs and should arguably to be united under the scientific name S. vulpinus. The specific name is a compound of uni which means "one" and maculatus meaning "spotted", a reference to the single blotch in the lateral line where the spiny and soft rayed parts of the dorsal fin meet.
The blotched foxface has a compressed body which has a depth which fits into its standard length 1.9 times. The dorsal profile of the head is steep to the rearof the eye and there is an indentation between the eyes. The caudal fin is forked. Like all rabbitfishes, the dorsal fin has 13 spines and 10 soft rays while the anal fin has 7 spines and 9 soft rays. The fin spines hold venom glands. This species attains a maximum total length of . This species is bright yellow with the head and front part of the body being white with a black band running from the mouth to the start of the dorsal fin and another black band extending from the shoulder to the chest. There is an irregular black spot or blotch on the centre to rear of the upper flanks.
