Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 49 - 54; Espinas anales: 0; Radios blandos anales: 32 - 38.
Body shape (shape guide): elongated.
Obligate air-breathing (Ref. 126274); Individuals can stay out of the water for 3 to 4 days at temperatures ranging from 10 to 15°C (Ref. 37350). They are typical ambush predators that lie waiting for prey on the bottom. They hunt mainly in the morning and in the evening, feeding primarily on fish (Ref. 12569). They mature at the age of 2 years and length of 30 cm. Spawning takes place in June and July (Ref. 56557). Eggs are pelagic. Utilized for human consumption.
