Glass frogs hold no secretsMother Nature Network Photographer Andrew Snyder writes, This glass frog (Hyalinobatrachium cf. cappellei) is a very small juvenile that was found on a small riverside branch along the Essequibo River on afternoon. Currently Guyana has six species of glass frogs recorded for the country, and many of those look quite similar to each other. This image shows clearly why glass frogs get their name, but is also a way to make species identification possible. The underside gives a clear view as to what color the bones are (typically either white or green) and whether certain organs such the heart are visible, all important diagnostic characteristics. -- source link
