Goniadidae Kinberg, 1866 |
Goniadidae is a family of marine worms within the Polychaeta. Goniadids have long, slender bodies and can grow up to 260mm in length, although most are less than 50mm long. [1] [2] Goniadids have an eversible proboscis with a circlet of chitinous jaws around the terminal end. [1] [3] [4]
Goniadids are highly mobile, burrowing predators which inhabit soft sediments, including sand and mud. [3] Goniadids tolerate a sediment mud content up to 60%, with an optimum range of 50-55%. [2] They are usually distributed within the intertidal and subtidal zones, from shallow water to offshore continental shelf sediments. [2] [4]
