Curacha also known as spanner crab or red frog crab is a local Chavacano name given to Ranina ranina, commonly found in the waters of Sulu province and Zamboanga and Bataan province. It is known as Kagang Pamah in Tausug, ipis dagat in Bataeños. It is a hybrid crustacean, with crossbreed characteristics of a large sea crab and a big spiny lobster. It is a large crab with a red color, which stays the same in color even when cooked. The crab is usually steamed or boiled so its flavor is preserved. Unlike most crabs whose majority of meat can be found in their claws, the motherlode of the curacha's meat is found in its body.
