I Characteristics of the inner ear in bony and cartilaginous fish. With the exception of the division of Chondrichthyes into Holocephali and Elasmobranchii, which is denoted by an asterisk, the phylogeny was modified. The number of species researched with regard to inner ear morphology is shown in bracketed numbers. ASC stands for the anterior semicircular canal, and PSC stands for the posterior semicircular canal. Macula utriculi (utr.): S, standard pattern, consisting of opposing ciliary bundles in the striola region and radially orientated ciliary bundles on the cotillus; The horizontal groups in the anterior region of the macula sacculi (sac.) are caused by the orientation of the ciliary bundles, which follow the curvature of the macula. Numbers show the number of ciliary bundle orientation groups; O stands for opposed ciliary bundle groups, and V for vertical ciliary bundle orientation.
