Flabelligeridae is a family of polychaete worms, known as bristle-cage worms, notable for their cephalic cage: long slender chaetae forming a fan-like arrangement surrounding the eversible (able to be turned inside-out) head.[1][2] Unlike many polychaetes, they also have large, pigmented, complex eyes.[3][4]

The first species was Amphridite plumosa, described from Norway. Flabelligerids were placed in various similar polychaete families until Saint-Joseph erected the family (under the name Flabelligeriens) in 1894.[5][7]

Mazopherusa is a possible fossil example from the Carboniferous; other fossil material is only dubiously assigned to the family.[1] The Cambrian Iotuba also may belong to the family, however it also appears similar to Acrocirridae.[8]
