I was not aware that it was World Frog Day today! The use of frogs in science have contributed to many important discoveries such as the first report of chemical neurotransmission, embryo development, gene isolation, pregnancy tests, and photoreceptor function and assembly. 🧪 🐸

An image of a Xenopus laevis frog. They are a large, green mottled aquatic frog with fairly small eyes compared to their bodies. This is the model that I use to study vision in my lab.
This is an image of a whole sectioned frog eye. It includes the sclera (white of the eye), the choroid (blood supply), the retina (neural tissue that senses light), the lens (bends light), and the cornea (clear tissue at front of the eye).
An image of a frog retina that shows the photoreceptor outer segments (purple), the cone inner segments and bipolar cells (green), nuclei (blue), and the retinal pigment epithelium (orange).
An image of developing frog eyes and brain. The red represents early rods and the green early cones.
