Oriental flying gurnard (Dactyloptena orientalis)

Dactyloptena orientalis is a species of marine fish in the family Dactylopteridae. Their name is derived from the French word ‘gurnard’ meaning to grunt, for the grunting sound this fish makes. The oriental flying gurnard can grow to 40 cm (16 in) in length but its common size is about 20 cm (8 in). The Oriental flying gurnard is widespread throughout the tropical waters of the Indo-Pacific region including the Red Sea. The pectoral fins are normally held against the body, but when threatened the fins are expanded to startle potential predators which may include sea breams and mackerel. The flying gurnard uses its pelvic fins to walk along the bottom of the ocean.The oriental flying gurnard feeds on small bony fish, bivalves, and crustaceans.
