Examination of the original material of Ikeda taenoides by Teruaki Nishikawa in 2002 showed that the longitudinal muscle layer lay between the circular layer and the oblique layer, as in all other echiurans, throwing the validity of the family Ikedidae into doubt. Nishikawa advocates that the family be regarded as a junior synonym of Echiuridae.[3]
