Today we have a truly uncommon creature in the form of a see-through frog. This strange little amphibian, often referred to as a glass frog, comes in 60 different varieties and is most notable for its translucent skin that allows a rather immodest view of all its internal organs. From underneath, you can catch a scandalous view of its liver, heart and intestines. Living in southern Mexico, Central and South America, glass frogs prefer a tropical life in the lush rainforests, usually high in the treetops above the water. Certain species of glass frogs, however, are endangered due to habitat loss.
It is thought by scientists that these creatures evolved with invisible skin to act as a form of camouflage. Since they are typically high in the trees, looking up at bits of organs rather than seeing an actual frog is somewhat confusing for predators. Many species have white bones, but some sport green bones which add a little extra to the show when viewed through the skin. Unlike many other frogs, these little guys have eyes that face forward rather than to sides, giving them a unique appearance.
Glass frogs are night owls and like to sleep during the day and hit the town at night. Males have rather strong territorial instincts and get a little ticked if another male enters their breeding territory. To warn off the unwanted suitor, the frog makes a super strange, low intensity sound. If that doesn’t work, the frog jumps around wildly on top of the intruder until it gets the message and goes away. After a successful mating session, the female lays 20 to 30 eggs, which are also transparent removing all need for a sonogram. Don’t forget to mention an uncommon creature you’d like to see doodlewashed in the comments!
