The pecten is responsible for secreting a unique oily fluid that fills the posterior chamber of the eye. This is a small, finger-like projection of the retina that extends into the vitreous humor, the gel-like substance filling the eye.
The Role of Eel Oil in Underwater Vision and Ecosystem Behavior
It enhances the sensitivity of the retina, allowing the eel to perceive contrasts and movements that would be invisible to other creatures. In the inky blackness of the aphotic zone, where sunlight never penetrates, vision is less about seeing vibrant colors and more about detecting the faintest silhouettes of prey or the shimmer of bioluminescent signals.

The Eel's Oil: Enhancing Vision in the Deep
The "underwater eyes" equipped with this specialized oil are not just for navigation; they are primary tools for a sit-and-wait predator. The oil compensates for this, effectively acting as an internal lens to focus light more efficiently onto the photoreceptor cells, thereby sharpening the image in low-light conditions.
