What frog acts like a paratrooper? What frog has see-through skin? What will some frogs do to protect their eggs? What is a pacman frog? In my last blog, I wrote about giant frogs and tiny colorful frogs that could kill you. Now I’m on to some other interesting amphibians!
Some Glass Frogs, which include species from the Centrolenidae family, have translucent skin, which allows one to see the interior organs! The eggs of pregnant females can also be seen as well! Glass Frogs are quite small, with an average size of 1-3 inches. Members of the Centrolenidae family can be found near forested rivers and streams in Central and South America. They spend much of their time in the forest canopy, where they hunt for insects and other small arthropods. I’m thinking of writing a book on how to dissect these frogs and calling it “Through the Looking-Glass Frog”.
Whereas many species of frogs lay eggs directly into ponds, pools, or vegetation, frogs from the family Hemiphractidae have the ability to carry their eggs with them. Some of these species are equipped to transport eggs hidden in a dorsal pouch, which allows better protection of the eggs from predators and extreme conditions. Though many frog species have a larval stage (tadpoles), some species, such as the Horned Marsupial Frog (Gastrotheca cornuta), keep the eggs until they develop and hatch into live froglets!

The Surinam Horned Frog (Ceratophrys cornuta) can grow to 8 inches long and weigh over a pound. Because they have large mouths and a voracious appetite, eating almost anything that comes near them, they are sometimes called “pac-man frogs”. These frogs generally ambush their prey, camouflaging themselves in mud or leaf litter, and quickly striking and swallowing prey whole! Horned frogs have been known to devour prey such as crickets, centipedes, small mice, fish, other frogs, dots, and blue ghosts. Sometimes they try to swallow prey that is too large and are found dead with the intended prey sticking out of their mouths! This happened recently when a horned frog was fed Donald Trump’s ego. The purpose of the horn-like projections is unclear, though they may serve to aid in camouflage.
Finally we come to Wallace’s Flying Frog (Rhacophorus nigropalmatus). Though these frogs don’t technically fly, they can use their thickly-webbed feet and large toe pads to glide through the air for distances of over 15 meters! These frogs live an arboreal life in the tropical jungles of Borneo and Malaysia. They usually use their super gliding abilities when attempting to escape a predator or hunt prey. Flying frogs also have loose flaps of skin, which aids in their gliding. They often breed and lay their eggs in pools formed by rain or in pits made by wallowing animals such as rhinos. As their Latin name suggests, they have black coloring on their feet. Scientists are currently researching this species in an effort to apply the frog’s gliding capabilities to human soldiers and pizza deliveries.
Hopefully you’ve enjoyed this little foray into the world of frogs! Frogs are pretty diverse and amazing creatures! Now if you’ll excuse me, I’m going to hide in a mud pit, cover myself with leaves, and snatch some unsuspecting prey.
