Etymology
From its color.

The rather unattractive but delicious redfish is part of the large scorpaenidae family. These two species live in the cold waters of North Atlantic.

Redfish have a short body with a large head and wide, gaping mouth. They have a row of short dorsal spines followed by a flat dorsal fin and a small tail with a shallow indent.

Adults range in colour from bright orange (S. marinus) to bright red (S. mentella). S. marinus grow to a maximum length of about 70 centimetres, while S. mentella grow to about 60 centimetres. Much as the age of a tree is calculated by counting the rings in its trunk, the age of a redfish is determined by counting the rings on the otoliths (small bones in the fish's middle ear). They often live to be 40 years old.
