Measurements of visible retinal layers in the ventral retina of Teuthowenia pellucida.

“Location” indicates region in which the photoreceptors were measured: central portion of the equatorial retinal (C) or in the periphery (P). The photoreceptor outer segment (OS), ommin band, and inner photoreceptor segment (IS) make up the total photoreceptor length (PR), which ranged from 75–380 μm. Total retinal thickness refers to the length of the supporting cell layer and photoreceptors together (105–440 μm).* Asterisk indicates an approximation due to damaged layers.
