Dec 18, 2011: On this frog with golden eyes we can see the eardrum located behind it's eyes.

By the way, one more interesting fact which I found via Google and checked IRL: before the use of refrigerators became wide-spread, frogs were used in villages to put into milk jugs so that the milk would not clabber. My Mom remembers time when refrigerators were rare, and my grand-ma witnessed housewives in villages pulling a frog, holding it by a hind leg, out of a milk jar before pouring some milk from the jar into a cup. Those who lived in cities got shocked on seeing this. Still, now I understand the roots of those stories about a frog who got into a milk-pail and churned milk into butter.

Later, scientists discovered that excretions of frogs' skin have microbicide effect.lenzoo-20111218
