Frenulata, "beard worms", is a clade of Siboglinidae, "tube worms". They are one of four lineages with numerous species.[1][2] They may be the most basal clade in the family.[3] Despite being the first tube worms to be encountered and described, they remain the least studied group. This is because of their slender shape, they often get destroyed as a result of being caught as bycatch or poor preservation. They are found primarily in deep, muddy sediments, cold seeps, and anoxic firth sediments.[4][5]
