The eggs of the spiny sea urchin that lives in the waters around the Aleutian Islands and southern Alaska are excellent food. Look for the sea urchins in tidal pools. Break the shell by placing it between two stones. The eggs are bright yellow in color. Most northern fish and fish eggs are edible.
Exceptions are the meat of the arctic shark and the eggs of the sculpins.
The bivalves, such as clams and mussels, are usually more palatable than spiral-shelled seafood, such as snails. The black mussel, a common mollusk of the far north, may be poisonous in any season. Toxins sometimes found in the mussel's tissue are as dangerous as strychnine. The sea cucumber is another edible sea animal. Inside its body are five long white muscles that taste much like clam meat.
