Biology     Glossary (e.g. epibenthic)

Can stay out of the water for 3 to 4 days at temperatures ranging from 10 to 15°C (Ref. 37350). Is a typical ambush predator that lies in wait for its prey on the bottom. Hunts mainly in the morning and in the evening, feeding primarily on fish (Ref. 12569). Matures at the age of 2 years and length of 30 cm. Spawns in June and July (Ref. 56557). Eggs are pelagic.
