FROGS
Best living environment for frogs
Frogs popular pets, but since they are amphibians
their requirements differ from that of the common
aquarium inhabitants. Some frogs spend most of
their time in water, while others a mostly land
dwellers. Always investigate the natural habitat and
living conditions for your frog or turtle before your
bring it home. It is also important to remember that
many species will grow quite large and might
outgrow their first home.
Many frogs live in the tropics some live in mashes like
the American bull frog and the one above the one
below is a tropic
Worlds smallest and biggest frog

The smallest frog
known today is the
Brazilian Psyllophryne
Didactyla, which is
commonly referred to
as the Gold Frog. It can
be found in the
Southern Hemisphere
mainly in Brazil
 The biggest kind of frog
is the Goliath frog
(Conraua goliath). They
come from Cameroon in
West Africa. Their bodies
can reach the size of
nearly a foot (30 cm)
long.(remember: their
legs are also AT LEAST
that long!!!!)
A rare frog
Rana okaloosae is a rare
species of frog found
only in western Florida
This species ranges from
34 - 49 mm in length,
with the female generally
being the larger of the
sexes. They have no
spots on their dorsal
surface and unlike other
members of the genus
Rana they lack webbing
between some of their
toes. They are dark green
with a yellow throat and
a black underbelly.
Tadpoles are brown with
dark spots on the tail and
light spots on the ventral
surface

A frogs diet
 There are many species of frogs, found all over the world
except in Antarctica. What do frogs eat? Frogs are
carnivorous, which means they eat other animals. Small
frogs eat insects, worms and snails. Some species eat small
fish. Larger frog species eat small reptiles and mammals,
like mice and lizards. Frogs do not chew, so all of their prey
is swallowed whole.

Certain frog species have a long sticky tongue that they use
to catch flying insects. It is amazing how quickly they do
this. The entire process of the tongue unrolling, catching
the fly and then rolling back into the mouth takes less than
a second. Frogs that do not have tongues use their fingers
to put food into their mouths.
Frog population
There are
approximately 4740
species of frogs around
the entire world. There
are about 90 species of
frogs in the United
States. Unfortunately
about 120 amphibian
species, including frogs,
toads and salamanders,
have disappeared since
1980. Historically one
species of amphibian
disappears every 250
years.
 This is the areas where frogs
live
Did you know…………
 Frogs don't need to drink the way we do: they
absorb water through their permeable skin.
 The world's tiniest frogs are smaller than a dime,
and the largest frog can grow to be longer than a
foot and weigh more than 7 pounds.
 Nearly one-third (32 %) of the world's amphibian
species are known to be threatened or extinct.
At least 42 % of all species are declining in
population, indicating that the number of
threatened species can be expected to rise in the
future
Frog predators
Here are a few frog predators snakes
turtles
terrestrial and aquatic lizards
crocodiles
people (us)
terrestrial mammals such as hedgehogs and raccoons
some carnivorous, aquatic mammals such as water shrews
fish
diving birds, water birds and birds of prey (e.g. hawks, kites, eagles)
cane toads
