Stephanolepis cirrhifer
The fish grows to a maximum length of about 12 inches (30 centimetres), and consumes both plant material and small marine organisms like skeleton shrimp.The fish migrate wholly in ocean waters ("oceanodromous") between their feeding and spawning grounds, which can cover a range of over 100 kilometres (62 miles).Its diet includes kelp, but consists mainly of amphipods such as gammarids and skeleton shrimp, as well as the seagrass species Zostera marina.[8] Thread-sail filefish feed on fish, amphipods, isopods, cirripeds, polychaetes, pelecypods, seaweeds such as those of the genus Sargassum; and gelatinous plankton, such as the moon jellyfish Aurelia sp.[10] The thread-sail filefish is cultured and sold commercially as food in Asian countries, including Korea and Japan.
