It is interesting this is that large a news item. It would be good to see more testing and in varied areas to better understand general effectiveness. One of the folks at SAMS, Prof. Hart did a study in 2011, which concluded:
" A micro-spectrophotometry study of 17 species of shark found 10 had only rod photoreceptors and no cone cells in their retinas giving them good night vision while making them colorblind. The remaining seven species had in addition to rods a single type of cone photoreceptor sensitive to green and, seeing only in shades of grey and green, are believed to be effectively colorblind. The study indicates that an object's contrast against the background, rather than colour, may be more important for object detection."

Why didn t someone came up with this idea earlier? 😯
Couldn t find the report on the www.scam website. I wonder if it was tested for only the type of sharks in australia or also the types in the caraibian. Are all type of sharks colourblind? What i find amazing is that sight wins from smell for this predator.... |
