The longfins, also known as roundheads or spiny basslets, are a family, Plesiopidae, which were formerly placed in the order Perciformes or considered indeterminate percomorphs, but are now considered basal blenniiforms.^[2]^[3] They are elongated fishes, found in the Indian Ocean and western Pacific Ocean.
