Anchovies are small, green fish with blue reflections due to a silver-colored longitudinal stripe that runs from the base of the caudal fin. They range from 2 to 40 cm (0.79 to 15.75 in) in adult length, and their body shapes are variable with more slender fish in northern populations.
The snout is blunt with tiny, sharp teeth in both jaws. The snout contains a unique rostral organ, believed to be sensory in nature, although its exact function is unknown. The mouth is larger than that of herrings and silversides, two fish which anchovies closely resemble in other respects. The anchovy eats plankton and recently hatched fish.
Not only is fish delicious, it’s good for you. A low-fat, high-protein powerhouse packed with omega-3 fatty acids, fish offers a wide range of health benefits, from keeping your brain and heart functioning properly to helping ease symptoms of depression, and even keeping your skin and hair looking radiant.
Medical evidence suggests that eating fish on a regular basis—two or three times a week—may help to reduce the incidence of heart disease.
Feeling blue? Eat some fish. Research has discovered links between low omega-3 levels and higher incidences of depression, seasonal affective disorder, and postpartum depression.
