The barrel gurnard ( Trigla lyra ) or also called barrel cock is a species of fish from the subfamily of the real gurnard ( Triglinae ) in the family of gurnards (Triglidae) and the only representative of the genus Trigla .
Occurrence
The lyre gurnard lives on a sandy bottom in water depths of up to 400 meters. It occurs in the Mediterranean and the eastern Atlantic to the Channel coast as the northern border; from Northern Britain and the North Sea to the coast of Namibia . The organ cock is not found in the Black Sea.
features
Typical of the genus Trigla, there are no large, ossified shields on the sideline of the lyre gurnard. In addition, the scales on the sidelines are not bribed. For this purpose, the tip of the snout is provided with 2 serrated plates, between which there is a deeply forked incision. The length of the lyre gurnard is usually 25 to 40 cm, but can also reach 50 cm. The fish is red in color, with its 1st dorsal fin , pectoral and pelvic fins bordered in blue. In total it has two dorsal fins. The snout is extended forward by two separate plate lobes. In addition, the side plates of the head are provided with long spines, one of which extends up to half the length of the pectoral fin. This type of gurnard is also characterized by long pectoral fins that extend to the first third of the anal fin . The three front rays of the pectoral fins are, as with all gurnards, free rays that function as free, flexible "feet". These enlarged rays or spines are also used as feelers on the sea floor and are provided with taste buds .
Way of life
The lyre gurnard lives on the seabed and moves with the help of its "little feet". At the end of these 3 free finger-shaped pectoral fins there are taste buds that can be used to track down prey. It eats crabs , mollusks and small fish. With the help of the well-developed swim bladder , the lyre-gurnard, like any gurnard, can make growling noises under water. The organ gurnard spawns in winter and has planktonic eggs.
