Description

The ocellate scorpionfish is a small species of scorpionfish, reaching about 8.0 cm in length. They generally have mottled brown, orange, and white scales with twelve dorsal spines, eight to nine dorsal soft rays, three anal spines, and five anal soft rays along with a quadrangular, naked depression behind the eyes. Ocellate scorpionfish also feature sexual dimorphism,[4] adult males will usually have a large black spot toward the rear of the dorsal fin between spines eight and ten. Females and juveniles will lack the spot or only feature a faint one.[5]

Behavior

Ocellate scorpionfish are generally more nocturnal, venturing out most often at night while remaining immersed within reefs during the day.[6]
