Extraocular muscles are classically grouped as four rectus and two oblique muscles. However, their description and potential associations with species behavior are limited. The objective was to characterize extraocular muscles in four Myliobatoidei rays from diverse habitats with divergent behaviors. Heads (10 per species) of Dasyatis hypostigma, G...

... Similar to mammals, in fish, the eye muscles are responsible for the movement of the eye. The eye muscles are not uniform among species and vary in number and shape according to differences in fish species' habitats; however, information on the eye muscles in different fish species is scarce (Cunha, Oliveira, & Kfoury Jr, 2016). Generally, there are four rectus and two oblique muscles; during eyeball movement, the inferior and superior rectus muscles are responsible for movement around the horizontal axis of the eyeball, while the medial and lateral rectus muscles are responsible for movement around the vertical axis. ...
