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. They are elongated fishes, found in the Indian Ocean and western Pacific Ocean.
