Where Do You Find Frogs?
· Frogs can be found everywhere on earth except Antarctica, with almost 5,000 known species.
· Most frogs do not live in the water, only near it.
· Female frogs are hard to find as they are silent most of the time.
· Reduction of the frog population, especially in Asia and developing
countries, causes increase in diseases carried by mosquitoes, since
frogs eat thousands of mosquitoes every day.
· The purple frog, recently rediscovered in India, has almost no head, a
pointed pig snout nose, and sounds like a chicken when it speaks.
. Frogs are cold-blooded which means that their bodies are the same temperature as the air or water around them.
Toads vs. Frogs
· Frogs need to live near water, but toads do not.
· Frogs have eyes that are set higher, are rounder, and bulge out of
their head. Toads have eyes that are set lower on their head and are
shaped like a football.
· Frogs have smooth skin that is moist and looks slick. Toads have dry skin with bumps on it.
· Frogs jump high and long. Toads will not jump, but only hop or actually run if they have to.
· Frogs have many predators, but the skin of a toad has a bitter taste
and scent that burns the nose and eyes of anything that bites it.
Size isn't Everything!
· The Amazon Horned Frog is about the size of a coffee cup and uses its
woodsy coloring to bury into the underbrush with only its head above
ground. If anything comes by, the size of its own body or smaller, it
leaps out and swallows it hole, using its sharp teeth.
· The Goliath Frog is the world’s largest, found in Cameroon, in Africa.
Their bodies can get to one foot in length, and their legs are at least
· The Gold Frog, measuring half an inch, has always been the smallest
frog in the world, but in April 2009, a new species was found in the
Andes Mountains in Peru. The female measures up to .49 inches and the
male only .44 inches.
· In America, the bullfrog is the largest of the species.
· Frogs do not keep on growing throughout their life cycles. They stop growing at the average height for their species.
. Scientists have found frogs fossils that date back to the Jurassic period over 140 million years ago.
· Frog eyes bulge outward to enable them to see in all directions, though their eyes appear to stare blankly.
· Frogs can retract their eyes and when they do, they bulge inward in their mouths and help them swallow their food.
· Some frogs have a patch on top of their heads which is like a third eye. It reacts to light to aid the frog in navigation.
· Frogs also have a third eyelid which helps protect their eyes underwater and keeps them moist on land.
· A frog can only see moving things. It could literally starve to death with live prey in front of it if the prey never moved.
Frogs and Water Don't Mix
· Frogs live around any water source, such as swamps, marshes, lakes,
rivers, streams, and temporary pools of water caused by flooding or
· The North American Wood Frog is the only species of frog found above
the Arctic Circle and in winter it actually freezes, its heartbeat
stops, and it thaws again in spring, coming back to life.
· Frogs can be found living in deserts, mountaintops, rain forests, tundras, and caves.
· Frogs can adjust their life cycle timing to adapt with their habitat.
If they live in a desert area with little rainfall, they can actually
lay their eggs in a wash as soon as rainfall begins, and the eggs will
go from tadpole to frog in as little as ten days.
· African Dwarf Frogs live mostly underwater, coming up for air every now and then.
· Frogs can jump over 20 times their body length.
· The longest jump ever recorded was 33.6 inches, at a South African frog derby.
· Tree frogs have pads on their toes with tiny bumps that cause friction, even on wet surfaces.
· The flying tree frog of Costa Rica uses the webbing between its toes to act like parachutes as it leaps from tree to tree.
· The study of how frogs adhere to slippery surfaces is being used to develop anti-skid devices in human technology.
· Frogs breathe with three parts of their bodies: skin, mouth, and a
membrane covering the inside of their mouths. Their skin takes in oxygen
from their environment. They inhale and exhale through their mouths.
· A frog’s sticky tongue is used like fly fishing. When it sees a meal,
it casts out its tongue and reels it back in to swallow the meal.
· Some frogs like the Squirrel Tree Frog have large sacs that expand to
resonate sound. Some frogs can make sounds without any special sac.
· Frogs call out for different reasons: mating calls, territorial calls, weather announcement calls, and cries for help.
· Male frogs are the only ones who sing, to attract mates and warn off
other males. Females listen to the mating song and choose a mate on
which one is the loveliest.
What Do Frogs Eat?
· Frogs are carnivores, meaning they eat meat. The largest of frogs eat
snakes, turtles, mice, chicks, bats, and even smaller frogs.
· Small frogs eat insects like flies, mosquitoes, and dragon flies, but
they will also eat snails, worms, small fish, and spiders.
· Frogs don’t drink water the way we do, but absorb it through their
skin. Some frogs have places on their bellies which also absorb water.
· Some frog species have teeth to help them hold their live prey, but they do not chew.
· Frogs who have no tongues use their fingers to catch prey and put it into their mouths.
Colors of Frogs
· Most frogs are either brown and earthy tones or green to blend in with foliage.
· Some frogs stand out with their bright colors and stripes to say, “I’m poisonous.”
· Some frogs are imitators of poisonous ones, like the poison dart frog.
· The fire-bellied toad uses flash color, where he only displays his
bright colors under threat of attack, which confuses predators and
provides time for escape.
· Some species, like the Chilean Four-Eyed frog, has a pair of bumps on
its rear that are hidden until it’s in danger and by lowering its head,
the larger rear portion appears to be the head of a larger frog than it
Don't Pick on Frogs!
· Most metal sheds can be a death trap to frogs if they contain herbicides, pesticides, and other chemicals poisonous to frogs.
· Some frogs use camouflage by remaining one color in a season and changing with the surrounding foliage the next season.
· The most poisonous animal is the Golden Poison frog which with a single touch of its skin can kill ten humans.
· Some toads can live up to 40 years, but of the frogs, poisonous ones live from seven to 17 years.
· A frog in captivity, if cared for properly, will generally live much longer than those in the wild.
· A tadpole is also known as a polliwog.
· Frogs lay anywhere from hundreds to thousands of eggs, in water, and the males fertilizes them.
· Tadpoles vary in characteristics from species to species. Scientists
are beginning to be able to tell the frog species apart by their
· One species of tadpole, the Axolotl, is actually a salamander that
never grows to be an adult lizard, but retains its gills and fins and
procreates at this stage.
· Though most frogs abandon their eggs, some frogs carry the eggs on
their backs, in their mouths, and the Marsupial Frog has a pouch for
Man and Frog
· Before touching a frog, always wash your hands and do not dry them.
Sunscreen and insect repellant on human hands will kill a frog or toad.
· Australian Tree Frogs emit a chemical substance that heals wounds on humans.
· Frogs can enter a state of relaxation by turning it over on its back and gently rubbing its belly in a circular motion.
· Warts cannot be transmitted from toads or frogs. This is a myth.
