Bluehead Tilefish

Interesting Info

• The Bluehead Tilefish (Hoplolatilus starcki) occurs in Australian waters on the Great Barrier Reef and Coral Sea (Queensland), and on offshore reef systems of north-western Western Australia including the Rowley Shoals and Scott Reef.
• Globally, it is found across the tropical Indo-Pacific from Indonesia and Papua New Guinea to the Philippines, southern Japan, Micronesia, and the Solomon Islands.
• This species lives much deeper than most reef fish, which is why it is rarely seen.
• It inhabits steep outer reef slopes and drop-offs rather than shallow coral reefs or lagoons.
• Adults typically grow to about 30 cm (12 in) in length, giving them a long, slender appearance compared to chunky reef fish.
• The head is bright electric blue with yellow markings, while the body is pale blue to white, making it one of the most colourful tilefishes.
• The tail fin is deeply forked and often edged in yellow, helping divers identify the species from a distance.
• Juveniles look similar to adults but are paler and usually stay closer to shelter along the reef slope.
• Unlike burrowing tilefishes, this species does not dig tunnels in sand, instead hovering close to rocky ledges and reef faces.
• It feeds on small fishes and mobile invertebrates that drift past reef slopes, snapping prey from the water column.
• Bluehead Tilefish are usually seen in pairs or small loose groups rather than large schools.
• They hover above the reef face facing into the current, darting out to grab food before quickly returning to cover.
• Reproductive behaviour has not been well studied, but like other tilefishes they are believed to spawn in the water column.
• Lifespan data are limited, but deep-slope tilefishes are generally thought to live for many years due to slow growth.
• Because of their depth range, most sightings come from deep dives, submersibles, or high-quality underwater photography rather than casual reef visits.
