Presented live on Tuesday, June 4, 2024 for Behavior Education Patreon community members. This was recorded during the live class.

NOTE: In this presentation we discussed Fovea and their absence in snakes as well as eyes eye structures that we now have updated information about thanks to more recent studies. Please see Part 2 and Part 3 for more information as well as the references list below.
