胸鳍的内面没有鳞片。 整体的色彩是银色或微白色的, 时常淡褐色或橄榄色在上侧面上。 在侧边上的每个鳞片有一个褐色斑点形成纵列。 鳍均匀地是清澈的到些微淡黄色。 新鲜的标本在侧边上有分散的褐色斑纹。 经过眼的一条黑色的横带也可能是明显可见的。
Generally solitary over sand or rubble areas adjacent to reefs . Feeds mainly on benthic invertebrates. Sometimes has a distasteful iodine flavor; however, untainted fish are good to eat.
通常独居性的沙子之上或碎石邻近礁的区域。 主要吃底栖的无脊椎动物。 有时有一个味道差的碘滋味; 然而，没被污染的鱼是好吃。
