Australian scientists have conducted a study using micro-spectrophotometry which shows that some sharks might not be able to differentiate colors.
Researchers from the University of Western Australia measured the eyes of some shark species found in Australian waters, which revealed that the animals’ retinas contain only one type of cone photoreceptor, a cell that measures color vision by reviewing light at specific wavelengths.
“Humans have three cone types that are sensitive to blue, green and red light,” said the lead author of the study, associate professor Nathan Hart. “By comparing signals from the different cone types we get the sensation of color vision.”
Conducting in tandem with Australia’s University of Queensland, the study is part of a project aimed at finding a way to limit shark attacks by providing swimmers with special attire, a foreign news channel reported.
“Our study shows that contrast against the background, rather than color per se, may be more important for object detection by sharks,” Hart said. “This may help us to design long-line fishing lures that are less attractive to sharks.”
Scientists particularly focused on bull shark, an aggressive species that usually inhabits shallow, murky waters and is responsible for numerous attacks on humans.
“Most shark attacks are thought to be the result of curiosity on the part of a shark that has been attracted to an unusual stimulus, rather than some premeditated ambush,” Hart said.
