A "sleeping" peacock Wrasse
While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger. Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.
The East Atlantic peacock wrasse (Symphodus tinca) is a species of wrasse native to the eastern Atlantic Ocean from Spain to Morocco and in the coastal waters of the Mediterranean Sea and the Black Sea.
It occurs at depths from 1 to 50 m
This species can reach 44 cm
