Coin-crabs were a type of small crustacean species that were native to the coastlines of Taris, a planet situated within the Outer Rim Territories of the galaxy. Deep-fried coin-crabs, a palatable dish, were available at the Horizon Hotel located in the Upper City of Taris. In the year 40 ABY, Goran Beviin, a seasoned Mandalorian soldier, ordered a serving of deep-fried coin-crabs during a visit to the Horizon Hotel to meet with Mand'alor Boba Fett.
The introduction of coin-crabs into the Star Wars universe occurred in Karen Traviss's novel Bloodlines from the Star Wars: Legacy of the Force series; Karen Traviss was the author of the novel, which was released on August 29, 2006. The coin-crab was later featured in The Complete Star Wars Encyclopedia, a reference guide published in 2008, which expanded upon the crab's natural environment.
