Distribution by collection data
The Purple Flying Gurnard lives in a range of habitats including estuaries, coastal bays and deep sandy areas. It is often seen in water less than 10 m in depth, but is also caught in trawls down to 100 m.
Other behaviours and adaptations
The pectoral fins are usually held against the sides of the body. When the fish is disturbed, it quickly expands its pectoral fins, often retracting them before swimming off at speed. Despite its common name, the Purple Flying Gurnard does not fly. It can however "walk" on the bottom by alternatively moving the pelvic fins and short pectoral fin rays.
