Where is the frog?
by Tímea Haszpra, Eötvös Loránd University, Budapest, Hungary
Walking in the forest we noticed this frog among the dead fallen leaves and stones. As it became aware that someone was close to it, the frog became motionless thinking that we probably couldn't see it. Then the frog realized that this assumption was wrong, and jumped away.
