Sharks may be colorblind! According a research in Australia on 17 different species of shark retinas, only one kind of color-sensitive cell in their eyes. This means they might not be able to tell the difference between different objects based on the color. The findings could be useful in developing swim or surf gear, and long-line fishing lures to appear less "attractive" to sharks so they don't caught accidentally.
