Langostino
Langostino is a Spanish word with different meanings in different areas. In the United States, it is commonly used in the restaurant trade to refer to the meat of the squat lobster, which is neither a true lobster nor a prawn. Squat lobsters are more closely related to porcelain and hermit crabs. Crustaceans labeled as langostino are no more than long, and weigh no more than . Langostinos are not langoustes (spiny lobsters) despite a similar name (in Spanish, lobster is called ""). Also, langostinos are sometimes confused with langoustines (Norway lobster). In the United States, the Food and Drug Administration  allows "langostino" to be used as a market name for three species of squat lobster in the family Galatheidae: "Cervimunida johni", "Munida gregaria", and "Pleuroncodes monodon". In Spain, it means some species of prawns. In Cuba and other Spanish-speaking Caribbean islands, the name langostino is also used to refer to crayfish. In Argentina the name is used to refer to "Pleoticus muelleri", a kind of shrimp, while in Chile and Peru it refers to "Pleuroncodes monodon". Restaurant labeling controversies. In March 2006, Long John Silver's garnered controversy by offering a dish they called "Buttered Lobster Bites" without making  it clear in its advertising that these were made from "langostino lobster." The Federal Trade Commission ultimately launched an investigation into deceptive advertising practices by the chain, because Food and Drug Administration regulations require that anyone marketing langostino as lobster must place the qualifier "langostino" adjacent to the word "lobster," and Long John Silver's not only failed to do this, but ran a television commercial making use of an American lobster in a manner that the Commission concluded was contributing to the misperception that the product was American lobster. Upon being contacted by the commission, Long John Silver's  promptly terminated the television commercial campaigns, revised its website, and committed both to prominently placing the word "langostino" adjacent to the term "lobster" in all future advertising, and to revising its existing in-store materials accordingly within eight weeks, and on June 24, 2009, the Commission wrote to the chain to inform them that they had no intention of taking further action at that time. A Los Angeles Superior Court judge made no decisions in April 2006 on the matter when a class-action lawsuit was brought against Rubio's Restaurants, Inc., for selling "lobster burrito" and "lobster taco" that  were in fact made with squat lobster. In February 2016, Red Lobster was revealed to have been substituting the less-expensive langostino for lobster.
