Scarus randalli Schultz, 1958, p. 97, fig. 20, pls. 19C, 27A.
Characterized by having 6 or 7 median predorsal scales, 3 rows on cheek with 2 or 3 scales in ventral row, ii,12 pectoral rays, rarely ii,13; lips not covering teeth, white in young and females, green in adult males. Color pattern of adult males and females strikingly different: juveniles and adult females reddish brown, 5 dark lengthwise streaks alternating with light yellowish brown interspaces; all fins red; caudal peduncle and basal portion of caudal fin abruptly light yellowish or whitish. Mature males bright green, spotted with orange dorsally above lower edge of eye, below which head is green (pale in alcohol) with red markings; scales with vermiculations on lower sides. Caudal peduncle and caudal fin bright green (pale in alcohol), with an orange new-moon-shaped mark occupying basal part of that fin; anal and dorsal orange margined with blue; edges of both lips narrowly red then submarginally green.
Smith (1959, pp. 270, 279, fig. 2, pl. 41 H, I) has correctly referred S. randalli Schultz to the synonymy of this species and Randall (1963, p. 226) has shown that S. frenatus Lacepède is the adult male and S. sexvittatus is the female and immature stages.
Through an oversight, Pseudoscarus frenatus (not Lacepède) Bleeker, 1862 (p. 40, pl. 16: fig. 2), was not removed by Schultz (1958, p. 83) from the synonymy of S. frenatus Lacepède to that of S. flavipectoralis Schultz, 1958 (p. 52), where it belongs.
Callyodon pectoralis [not Cuvier and Valenciennes] Smith, 1956 (p. 15, pl. 42J), has been found to be an illustration of S. cyanognatus Bleeker, to which it is assigned in this paper.
I have studied recently collected specimens as follows: Dr. Steinitz loaned one 290-mm specimen from the Red Sea; two 96- and 210-mm specimens were collected by the IIOE in the Aldabra Islands; USNM 202666 was collected by the IIOE at the Comoro Islands; one specimen from Sta. HA67–5, Diego Garcia Atoll, 13 June 1967, is 290 mm in length. Dr. Randall collected three, 255–295 mm, at Papeete, USNM 202693 and 202694.

主要棲息於裸露的外海岩礁區,有時在很淺的水域中;稚魚則出現在潟湖內珊瑚與碎石之中。以啃食水底的藻類為生。通常為獨居性,但當進食時,常混入魚群中。
Scarus frenatus

Scarus frenatus is a species of parrotfish.[3] Common names include bridled parrotfish, sixband or six-banded parrotfish or vermiculate parrotfish.[1]
Description
This species grows to a maximum length of 47 cm,[2] and can be distinguished by its patterns and colouration. Its appearance changes during its life phases. During the initial phase, it has a reddish to brown colour, six to seven dark, horizontal stripes along its body, and red fins.[4] In males, during the terminal phase, the posterior of the body and the lower half of the head appear abruptly lighter. Also, in males, the caudal fins appear blue-green with a large, orange, crescent-shaped area.[4]
Distribution
Scarus frenatus is found in the Indo-Pacific region from the Red Sea to the Line Islands and Ducie Island, and as far north as southern Japan, to its southernmost location at Shark Bay in Western Australia, Lord Howe Island, and Rapa Iti in French Polynesia. It is not found in the waters of Hawaii.[2]
Habitat and behavior
Normally, the bridled parrotfish occurs at depths of 1–25 m[2] on exposed outer reefs, occasionally in extremely shallow water. Juvenile specimens may be found in lagoons living within the rubble and coral of the reefs.[2] This species is generally a solitary fish. While feeding, it may join schools of mixed species.[2] It grazes on algae growing in the benthic zone.[2]
Parrotfish (
Scarus frenatus) are reef fish commonly found in the Kuroshio Current reef systems.
