Sea cucumbers are echinoderms—like starfish and sea urchins. There are some 1,250 known species, and many of these animals are indeed shaped like soft-bodied cucumbers. All sea cucumbers are ocean dwellers, though some inhabit the shallows and others live in the deep ocean.  Nutritionally, sea cucumbers have an impressive profile of valuable nutrients such as Vitamin A, Vitamin B1 (thiamine), Vitamin B2 (riboflavin), Vitamin B3 (niacin), and minerals, especially calcium, magnesium, iron and zinc.

Albacore is one of the smaller tuna species, reaching sizes between skipjack and yellowfin. They are bullet-shaped with a dark blue back and lighter blue-gray sides and belly. Albacore tuna also have very long pectoral fins and live for around 12 years.  Albacore tuna is a great source of heart-healthy omega-3 fatty acids. The omega-3 fatty acids found in albacore tuna may help lower your risk of heart disease, may help lower triglycerides, and may minimize the advancement of atherosclerotic plaques and halt arrhythmias.

Red sea urchins are found in the Pacific Ocean, from the coast of Alaska and the Aleutian Islands to Baja California in the east, and in the west, from Siberia to the northern reaches of Japan. They prefer rocky, protected areas of the ocean in shallow water close to shore, though occasionally they are found as deep as 100 metres. In Canada, the main fishery is located off the coast of British Columbia.  Like many other seafood, they're low in calories, low in fat, low in carbs and super-rich in proteins. They definitely make a good addition to your healthy diet.
