Researchers in Australia have discovered a weakness of one of the ocean's most fierce predators. Sharks, it seems, are completely color blind, according to?BBC.
The scientists, who examined retinas of 17 different species of shark, discovered the creatures have only one type of color-sensitive cell, known as a cone cell, in their eyes.
Human eyes have three cone cell types, with each type dedicated to receiving blue, green or red light. This allows most people to distinguish among different colored objects.
The research could help to prevent shark attacks on humans and assist in the development of fishing gear that may reduce the number of sharks caught accidentally in long-line fisheries.
