Evolution of Large Eyes in Stromboidea (Gastropoda): Impact of Photic Environment and Life History Traits

A. R. Irwin, N. W. Roberts, E. E. Strong, Y. Kano, D. I. Speiser, E. M. Harper, S. T. Williams

This paper investigates the evolutionary factors driving eye size variation in Stromboidea, finding that depth, activity patterns, and escape behaviors influence eye size and structure.

A morphological basis for path dependent evolution of visual systems

R. M. Varney, D. I. Speiser, J. Cannon, M. Aguilar, T. H. Oakley

The paper demonstrates path-dependent evolution of visual systems in chitons, showing that the number of optic nerve openings constrains the type of visual system that evolves.

The marine gastropod Conomurex luhuanus (Strombidae) has high-resolution spatial vision and eyes with complex retinas

A. R. Irwin, S. T. Williams, D. I. Speiser, N. W. Roberts

This paper measures the spatial resolution and contrast sensitivity of Conomurex luhuanus eyes and finds they provide high-resolution spatial vision with complex retinas containing more cell types than previously known.
