Trigla

Trigla is a genus of fish in the family Triglidae, commonly known as gurnards or sea robins. These marine ray-finned fish are characterized by their large heads, bony armor, and prominent pectoral fins. They are found in temperate and tropical waters worldwide, inhabiting both demersal and pelagic environments.

A distinctive feature of Trigla species is their modified pectoral fin rays. These finger-like appendages are used for "walking" on the seabed and for detecting prey through tactile and chemical senses. Some species also possess a swim bladder that can produce sounds, often described as grunting or croaking, which are believed to be used for communication or defense.

The diet of Trigla typically consists of small invertebrates and fish. They are often found foraging on the seafloor, using their specialized pectoral fins to uncover buried organisms. Their coloration varies widely among species, often providing camouflage against their benthic surroundings.

Commercially, several Trigla species are important food fish in various regions. They are caught using a variety of methods, including trawling and netting. Their flesh is generally considered firm and white, suitable for various culinary preparations. Conservation status varies for different species within the genus.
