Fig. 2

Ultrasonographic images of the eyes of four different species of sea turtle with different body weights: Caretta caretta (A), Chelonia mydas (B), Eretmochelys imbricata (C), and Lepidochelys olivacea (D), taken at the same transducer frequency and the same scale size (note the ruler to the right of each image). Similar structures at the level of the central optic axis are indicated by coloured lines as follows: corneal thickness (a), anterior segment depth (b), lens axial length (c), vitreous chamber depth (d), and axial globe length (e). Note the evident difference in size, especially the depth of the vitreous chamber and the axial length of the globe
