Geryons, commonly known as deep-sea red crabs or geryonid crabs, are a group of large, deep-water crustaceans prized for their sweet, delicate meat. These crabs typically inhabit the continental slopes and deep-sea environments of the Atlantic Ocean, particularly off the coasts of North and South America, Europe, and Northwest Africa. The leading countries involved in the commercial harvest of Geryons—often categorized as "not elsewhere included" in global fisheries statistics—include the United States (notably off the Mid-Atlantic coast), Spain, Portugal, and Morocco. These nations operate specialized deep-sea trawl and trap fisheries targeting Geryon species such as *Chaceon quinquedens* (the red deep-sea crab) and *Chaceon affinis*. The industry is relatively small compared to other crustacean fisheries but is valued for supplying high-end seafood markets, particularly in Europe and North America, where the crabs are sold both fresh and frozen. Sustainable management practices are increasingly important in these fisheries due to the slow growth and late maturity of Geryon species, making them vulnerable to overfishing.
