Shrimps are swimming crustaceans with long, narrow muscular abdomens and long antennae.
Northern shrimp (Pandalus borealis) is a sub-Arctic species, widespread in the northern parts of the North Atlantic and the North Pacific Oceans.
The shrimp has a remarkable life cycle. At sexual maturity, it first becomes a male but later changes its gender and turns female. This happens at the age of 2-6 years in different waters, depending on environmental conditions (mostly sea temperature).
Shrimps have high levels of omega-3 fatty acids and low levels of mercury. As with other seafood, shrimp is high in calcium, iodine and protein, but low in carbohydrates.
