washing hands

blog_illl172-02 常清洗食物的浣熊是否有潔癖?這只是人類把事情擬人化了。原來浣熊的視覺很差,唯有把手洗乾淨,使觸覺更清晰,讓自己可好好摸清楚手中的食物。 why does raccoon wash their food before eating? they actually don’t do that. raccoons have poor eyesights; washing their hands would give them a more sensitive touch, so they could get a better idea of what food is in their hands. http://www.mnn.com/earth-matters/animals/blogs/why-raccoons-wash-their-food-before-eating
