courtnek Posted September 7, 2004 Posted September 7, 2004 Cells may be concentrated in a horizontal "visual streak" across the retina. This provides more sensitivity to movement along a horizontal field of view. Wolves have a pronounced visual streak. Other animals, such as humans, have cells concentrated in a central area, called the "area centralis." This allows better focus up close. this makes perfect sense to me. Wolves have to both see (farsightedness) and smell, game fairly far away. Once closing in on the kill, they use their noses and sense of movement to take down the prey. They dont really need to focus up close, the prey has been chosen, and in most cases is running, so it's not hard to follow and take down. I am farsighted. I have to wear glasses to see things up close, but at a distance longer than my arm things get clearer the farther away they are. However, I could detect movement up close, no matter whether its blurry or not. Quote
imported_Matty Posted September 8, 2004 Author Posted September 8, 2004 "Perhaps because the shorter nose gives them a more human-like appearance, but perhaps it also results in behavioral changes so that these breeds are less likely to act like a running predator and hunt in packs and are more likely to be able to focus on human faces, using their area centralis." I found this interesting about the difference between long nosed dogs and short nosed dogs. Quote
