10 lb Box of Frozen Lobster Tails at Costco

Costco Lobster Tail Frozen

10 pound boxes of frozen lobster tails at Costco are now in-store for the Summer season! But there’s one important issue…the sign on the freezer case as well as the item price tags state “Cold Water Lobster” but the actual boxes are labeled “Rock Lobster” which is also called spiny lobster and they are warm water lobsters. Warm water lobsters are smaller, do not have that buttery sweet flavor of a Maine Lobster, and do not have claws. They are caught in Mexico, the Caribbean, and other warm waters.

ProTip: Check the boxes carefully before you buy, and make sure you are getting the kind of lobster you think you are. Both are good but have different price points, and many may only be looking for cold water lobster.


Don’t get me wrong, rock lobster is also quite tasty, but it’s no cold water Maine lobster in my opinion. I didn’t have a chance to check with the manager at my store, but word to the wise I’d suggest you look carefully at the actual box before you buy if cold versus warm lobster tails matters to you!
